CANADIAN JOURNAL OF CARDIOLOGY INSTRUCTIONS FOR AUTHORS
The Canadian Journal of Cardiology (CJC) is the official journal of the Canadian Cardiovascular Society (CCS). The CJC is a vehicle for the international dissemination of new knowledge in cardiology and cardiovascular science, particularly serving as the major venue for Canadian cardiovascular medicine. The CJC publishes original reports of clinical and basic research relevant to cardiovascular medicine, as well as editorials, review articles, and case reports. Papers on health outcomes, policy research, ethics, medical history, and political issues affecting practice, as well as letters to the editor, are welcomed. The CJC accepts and publishes articles in the English language only. Manuscripts are received with the understanding that they are submitted solely to the CJC and that none of the material contained in the manuscript has been published previously or is under consideration for publication elsewhere, with the exception of abstracts. Redundant or duplicate publications will not be considered. Duplicate submission is a significant breach of scientific ethical principles and may result in sanctions. All statements and opinions are the responsibility of the authors. The CCS reserves copyright on all published material, and reproduction of the material, even by the authors, requires written permission. With submission of a manuscript, a letter of transmittal must include the following 4 statements:
1. All authors have participated in the work and have reviewed and agree with the content of the article.
2. None of the article contents are under consideration for publication in any other journal or have been published in any journal.3. No portion of the text has been copied from other material in the literature (unless in quotation marks, with citation).
4. I am aware that it is the author's responsibility to obtain permission for any figures or tables reproduced from any prior publications, and to cover fully any costs involved. Such permission must be obtained prior to final acceptance.Editorial Policy
Each issue of the CJC carries the following statement, to which the authors agree when they submit a manuscript for consideration:
- Statements and opinions expressed in the articles and communications herein are those of the author(s) and not necessarily those of the Editor(s), Society, or publisher, and the Editor(s), Society, and publisher disclaim any responsibility or liability for such material.
At the discretion of the Editor-in-Chief, submissions may be accepted for either print or online publication. Case Reports and Images in Cardiology papers are generally published online only. Word-count limits (see below) generally refer to all elements of the article, including the abstract, acknowledgements, references, tables, and figure legends.
Original Papers are generally limited to 5,000 words, including all elements (title page, abstract, text, references, tables, and figure legends) in the principal Microsoft Word file, except for brief summary, word count, and short title. Rare exceptions to the word length limit may be granted by the Editor-in-Chief for specific reasons.Editorials and Viewpoint Papers. Editorials are normally invited. However, unsolicited Editorials and Viewpoint articles are welcomed and will be submitted for peer review. The distinction between Editorials and Viewpoints is that an Editorial will generally present comments on an article (usually accompanying it in the same issue of the Journal), whereas Viewpoints will present comments on a topical and/or controversial issue in clinical or basic cardiovascular medicine. Editorials should cite the paper commented on as one of the references in the paper. Length for both Editorials and Viewpoint papers should be no more than 2,000 words including all elements (title page, text, references, tables and figure legends). No abstract or brief summary should be provided for Editorials. Viewpoint articles should include a 250-word unstructured abstract as well as a 60-word summary for online listing. Conflict of interest guidelines apply.
Cardiovascular Controversies - Point/Counterpoint. These are short articles presenting opposite positions of an area of controversy in cardiovascular medicine. They are usually invited, with 2 articles (1 for each side of the argument) invited at the same time, to be published together in the same issue of the journal. Length should be no more than 3,000 words including all elements (title page, abstract, text, references, tables, and figure legends). The abstract should be under 100 words and unstructured. A brief summary (< 60 words) for electronic TOCs should be provided, but is not included in word count. Conflict of interest guidelines apply.Review Articles may be invited but unsolicited articles are also welcome. Reviews should not exceed 7,000 words including all elements (title page, abstract, text, references, tables, and figure legends). They should include a 250-word unstructured abstract as well as a 75-word summary should be provided for online listing.
Systematic Review/Meta-analysis papers follow the same length and structure guidelines as Review articles, except their abstract should be structured (Background, Methods, Results, Conclusions), and they are executed according to standards for the appropriate article type.New Methods in Cardiovascular Research. This category will include reviews of important current methods as well as newly developed techniques and approaches. The focus will be mostly on new and evolving methods in clinical research (e.g. new forms of trial design, biostatistical approaches, etc) but may also include fundamental work.
The guidelines will follow those for original articles if the manuscript describes the development of a specific new technique or method (see Original Articles in Article Classifications section). If the article is a review of a method(s) used, it will follow guidelines for review articles (see Review Articles in Article Classifications section). These articles are generally invited, but the editors will also consider author-initiated submissions.
CCS Guidelines and Position Statements are definitive positions taken by CCS-mandated committees on areas of clinical importance for which there is a need of guidance on diagnostic and therapeutic management. The word limit is generally 10,000 words for CCS Guidelines and 6,000 words for Position Statements, including all elements (title page, abstract, text, references, tables, and figure legends). Additional materials can be included as Online Supplementary Materials (see below). Additional options for publication of more extensive documents that must be approved prior to submission are: 1) publication of the Executive Summary in the print journal with the full document available as an externally funded journal supplement, which will generally be industry-sponsored (see guidelines for CJC supplements at www.onlinecjc.ca); 2) exceptionally, a series of papers in a theme issue of the Journal. If funds available are sufficient for typesetting but not printing, the full document can be published online. In some instances for which the size and focus of a series of guidelines papers can be accommodated in a specific appropriate theme issue of the CJC, option 2) may apply. In case of doubt, the authors should consult directly with the Editor-in-Chief. All CCS Guidelines and Position Statements published in CJC should have an unstructured 250-word abstract. Because of the extensive review that CCS Guidelines and Position Statements undergo at the level of the Secondary Review Panel and the CCS Guidelines Committee, these papers will generally be reviewed by the Editor-in-Chief and his/her designate rather than being sent to external peer-reviewers.
Co-publication with other journals of Guidelines and Position Statements. In general, CJC does not favor co-publication. In instances in which another society or organization is involved intimately and officially with CCS in elaboration of the Guidelines or Position Statements, co-publication will be considered. In such instances, agreements regarding co-publication should be made by the parties concerned (CCS, CJC, and other participating societies/journals) at the onset of Guidelines/Position Statement committee deliberation.
Case Reports must be informative to those in clinical practice. Case Reports should address uncommon presentations and/or treatments of common conditions, provide new insights into pathogenesis, or represent a newly recognized condition. The author(s) should provide sufficient literature review to place the report into context. No more than 5 references and 2 figures will be accepted, and the length should not exceed 1,000 words including all elements (title page, abstract, text, references, tables, and figure legends). An abstract of no more than 100 words should accompany the article and a 60-word summary should be provided for online listing. For all Case Reports, conclude the Abstract and Discussion with a concise statement of the Novel Teaching Point(s) emerging from the case.Images in Cardiology papers demonstrate particularly insightful images used in the detection of cardiovascular disease. The imaging modality may be old or new. The text of submissions for this section should be limited to that necessary to describe the context and importance of the image(s) and should not exceed 500 words including all elements (title page, text, references, and figure legends). No more than 5 references and 2 figures will be accepted. No abstract should be included, but a 60-word summary (not included in word-count limit) should be provided for online listing. For all Iamhes in Cardiology manuscript, conclude the text with a concise statement of the novel element(s) or teaching point(s) that the image report adds to the literature.
In general, both Case Reports and Images in Cardiology are published online only. If the authors cannot include all materials they would like to make available within the word count/figure limits, additional figures, tables, text, etc. can be provided in a Supplementary Material section (see below).Journal News and Commentary papers are short non-scholarly papers that comment on the state of the journal or an issue. For example, this would include brief Forewords to supplement issues or comments by the editor about progress of the journal, new features being planned, changes to policies, etc. Such papers are limited to a maximum of 1,200 words and 5 references. They do not normally have display items, but a maximum of 1 figure or table can be included in exceptional cases to make specific points in a clearer fashion. No abstract or summary are to be included.
Training/Practice papers present information of interest to practitioners, such as practical technical and patient management instruction or matters relating to health policy and promotion, as well as guidelines for Canadian cardiovascular training programs. These papers are primarily intended for guidance in practice, health promotion and/or training and are not detailed scholarly items--scholarly analyses should be submitted in the appropriate category (Clinical Research, Systematic Review/Meta-analysis, Review papers, Translational Medicine, or Viewpoint). The text of submissions for this section should be no more than 1,500 words. No more than 5 references and 2 display items (figures and/or tables) will be accepted. An unstructured abstract of no more than 250 words should accompany the article, and a 60-word summary should be provided for online listing. Submissions are divided into 3 subsections: 1) Contemporary Issues in Cardiology Practice, which will highlight issues of relevance to clinical practice in the face of rapidly-advancing technologies and new medical knowledge, 2) Training in Cardiovascular Medicine and Research, which deal aspects relevant to cardiovascular clinical and research training programs, and 3) Health Policy and Promotion, which deal with matters relating to health policy and promotion.
Translational Medicine articles are generally invited, but unsolicited articles are also welcome. This section is intended to present reviews or meta-analyses dealing with novel scientific findings or concepts with important clinical relevance or application. Areas of potential application include (but are not limited to) physiology, pharmacology, molecular biology, genetics, genomics, pharmacogenomics, population science, etc. Word length and other guidelines are the same as for Review articles.Brief Rapid Reports are brief papers reporting the results of clinical or basic research that is limited in scope but time-sensitive and of unusual interest. Articles for this section will receive rapid editorial attention, with a decision generally provided within 2 weeks of submission, rapid (within 6 weeks of acceptance) online publication, and print publication in the next available issue. Papers submitted for this section will be accepted with at most minor revision. If major revision is needed, the paper will subsequently fall into the Original Papers category. The submission cover letter should explain why the article is considered appropriate for this category. Maximum length is 3,000 words (including title page, abstract, text, references, tables, and figure legends; but excluding Brief summary), with a 100-word abstract and a maximum of 3 illustration items (figures plus tables). A 60-word Brief Summary should be provided for online listing.
Letters to the Editor may deal with any subject of current interest to cardiovascular medicine. If the subject concerns a recent publication in CJC, the letter will normally be forwarded to the authors for comment. Both the letter and the response may be edited for clarity or brevity. Letters should not exceed 400 words, with no more than 4 references and 1 figure or table. Conflict of interest guidelines apply.Contact Information

Please submit your article via http://ees.elsevier.com/cjc/. General Guidelines
The manuscript should conform to the guidelines in "Uniform Requirements for Manuscripts Submitted to Biomedical Journals," 5th edition, prepared by the International Committee of Medical Journal Editors and published in N Engl J Med 1997;336:309-15 and Can Med Assoc J 1997;156:270-7, available online at http://www.cma.ca/mwc/uniform.htm.
The CJC will accept online submissions of original manuscripts through the Elsevier Editorial System (EES) at http://ees.elsevier.com/cjc. Manuscripts submitted through this online system can easily be tracked by the authors, editors, and reviewers through final disposition. The corresponding author of the manuscript will receive automatic email notifications as the manuscript proceeds through the system. To begin using this system, go to http://ees.elsevier.com/cjc. Click the "Register" link on the toolbar at the top left to input author demographics and set up an account. After registration is complete, a notice will be sent via email indicating a user ID and password. Use this information to log in as an author by choosing the "Login" link on the toolbar, and select "Submit New Manuscript." Follow the prompts to complete the submission according to the specifications below. Be aware that the manuscript (with abstract included within), each table, and each figure need to be prepared as separate files following the guidelines listed below. Contact the editorial office if you have any problems or questions. Your user ID and password can be changed at any time by logging into http://ees.elsevier.com/cjc with your user ID and password and then clicking the "Change Details" link at the top of the page.
It is important that the file be saved in the native format of the word processor used. The text should be in single-column format. Keep the layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular, do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc. When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also the Guide to Publishing with Elsevier). Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text. See also the section on Electronic artwork.
To avoid unnecessary errors you are strongly advised to use the 'spell-check' and 'grammar-check' functions of your word processor.
With submission of a manuscript, a letter of transmittal must be provided, including the following 4 statements: 1. All authors have participated in the work and have reviewed and agree with the content of the article. 2. None of the article contents are under consideration for publication in any other journal or have been published in any journal. 3. No portion of the text has been copied from other material in the literature (unless in quotation marks, with citation). 4. I am aware that it is the author's responsibility to obtain permission for any figures or tables reproduced from any prior publications, and to cover fully any costs involved. Such permission must be obtained prior to final acceptance.
Include the title (up to 150 characters in length, including spaces), authors' names (including full first name, middle initial, and family name), academic degrees and academic affiliations, and a short title of up to 45 characters (including spaces). Be sure that authors' names are listed as they should appear in MEDLINE. Provide the word count on a separate line. Provide the full name, exact mailing address with postal code, telephone and fax numbers, and email address of the corresponding author to whom communication, proofs, and requests for reprints should be sent.
For Original Papers, CCS Guidelines or Position Statements, Translational Medicine articles, and Review articles, on a separate page, provide a brief summary of no more than 75 words, which will appear in the online contents listing (and in the print issue for the e-only articles section, if applicable) to inform readers of the principal contents of each paper. For Case Reports, Images in Medicine, Training/Practice papers, and Brief Rapid Reports, a 60-word summary should be provided.
On a separate page provide an abstract of no more than 250 words (for Original Papers, CCS Guidelines or Position Statements, Translational Medicine, and Review articles) or 100 words (for Case Reports and Brief Rapid Reports) that summarizes the study and conclusions, with clinical implications indicated as appropriate. Original Papers should have a structured abstract, with the following sections: Background, Methods, Results, Conclusions. Abstracts for CCS Guidelines or Position Statements, Translational Medicine, Training/Practice papers, and Review articles, while the same length (250 word maximum) as those for Original Papers, should be unstructured (no Background, Methods, Results, Conclusions headings). In all cases, conclude the abstract with a succinct sentence that summarizes the most novel finding(s) and/or contributions of the paper and its (their) relevance.
Text files must be saved as Microsoft Word files. To ensure that the final, published version matches the electronic file, use one of the following fonts: Arial, Courier, or Times. The use of other fonts may result in missing symbols. The font size should be 12 points. Abbreviations must be defined at first mention in the text and should follow the form recommended in "Uniform Requirements for Manuscripts Submitted to Biomedical Journals." Appropriate headings and subheadings should be provided in the Methods, Results, and Discussion sections. References, tables, and figures should be numbered in the order of mention in the text. Authors should conclude the Discussion with a brief Conclusions paragraph summarizing the most important novel elements of the study and their relevance to cardiovascular medicine.
Divide your article into clearly defined sections. Each subsection is given a brief heading. Each heading should appear on its own separate line. Subsections should be used as much as possible when cross-referencing text: refer to the subsection by heading as opposed to simply 'the text'.
State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results. Results
Results should be clear and concise.
This should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.
The main conclusions of the study may be presented in a short Conclusions section, which may stand alone or form a subsection of a Discussion or Results and Discussion section.
Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).
Any and all relevant funding sources for the study should be listed, including funding from industry and peer-review funding (with grant numbers if available). Funding Sources should be indicated in a separate paragraph after the Acknowledgements section.
All potential conflicts of interest must be identified in this section. Potential conflicts of interest that should be disclosed include: relationships with pharmaceutical and biomedical device companies or other corporations whose products or services are related to the subject matter of the article, from which any of the authors may obtain potential financial benefits. Such relationships include, but are not limited to, employment by an industrial concern, equity or stock ownership by authors or family members, membership on a standing advisory council or committee, being on the board of directors or publicly associated with the company or its products, where the concern produces products whose value or perception could be influenced by the content of the article. Other areas of real or perceived conflict of interest could include receipt of honoraria or consulting fees or receiving grants or funds from such corporations or individuals representing such corporations. Intellectual property rights held by the authors for inventions relevant to the subject of the article should also be declared. Funding by peer-review grant agencies does not generally constitute a conflict of interest, unless the funding is for intellectual property development related to the material covered in the paper from which the authors stand to obtain potential financial gain. Peer-review funding relevant to the material covered in the paper that does not constitute a conflict of interest should be indicated in the Funding Sources section that precedes the Disclosures section. If there are no potential conflicts of interest, this should be designated by indicating "none" in the Disclosures section. Disclosures should be indicated in a separate paragraph after the Funding Sources section.
List funding sources in this standard way to facilitate compliance to funder's requirements:
Funding: This work was supported by the National Institutes of Health [grant numbers xxxx, yyyy]; the Bill & Melinda Gates Foundation, Seattle, WA [grant number zzzz]; and the United States Institutes of Peace [grant number aaaa].It is not necessary to include detailed descriptions on the program or type of grants and awards. When funding is from a block grant or other resources available to a university, college, or other research institution, submit the name of the institute or organization that provided the funding.
If no funding has been provided for the research, please include the following sentence:This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.
Please submit math equations as editable text and not as images. Present simple formulae in line with normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).
If you are submitting an article prepared with Microsoft Word containing embedded math equations then please read this (related support information). Electronic Artwork

Image 'polishing' is also available, where our illustrators take your image(s) and improve them to a professional standard. Please visit the website to find out more.
Figure legends should follow the References and tables in the same Microsoft Word file as the text of the paper. Type figure legends double-spaced, with figure numbers corresponding to the order in which the figures are presented in the text. Identify all abbreviations appearing in figures in alphabetical order at the end of each legend. Provide enough information to allow interpretation of the figure without reference to the text. Written permission must be obtained from the copyright holder (usually the publisher) to reproduce any previously published figures. Cite the source of the figure in the legend. Figure legends should not appear in the figures themselves.
Tables should follow the References and precede the figure legends in the same Microsoft Word file as the text of the paper. Tables must be created using Microsoft Word (.doc) or Excel (.xls). Type tables double-spaced on a separate sheet for each table, with the table number and title above the table and explanatory notes below. Table numbers should appear in Arabic numerals and should correspond to the order of the tables in the text. In a footnote to each table provide an alphabetical listing of all abbreviations used. Written permission must be obtained from the copyright holder (usually the publisher) to reproduce any previously published table or adapted table. Citation in Text
Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Unpublished results and personal communications are not recommended in the reference list, but may be mentioned in the text. If these references are included in the reference list they should follow the standard reference style of the journal and should include a substitution of the publication date with either 'Unpublished results' or 'Personal communication'. Citation of a reference as 'in press' implies that the item has been accepted for publication.
This journal encourages you to cite underlying or relevant datasets in your manuscript by citing them in your text and including a data reference in your Reference List. Data references should include the following elements: author name(s), dataset title, data repository, version (where available), year, and global persistent identifier. Add [dataset] immediately before the reference so we can properly identify it as a data reference. The [dataset] identifier will not appear in your published article.
Most Elsevier journals have their reference template available in many of the most popular reference management software products. These include all products that support Citation Style Language styles, such as Mendeley and Zotero, as well as EndNote. Using the word processor plug-ins from these products, authors only need to select the appropriate journal template when preparing their article, after which citations and bibliographies will be automatically formatted in the journal's style. If no template is yet available for this journal, please follow the format of the sample references and citations as shown in this Guide.
Users of Mendeley Desktop can easily install the reference style for this journal by clicking the following link:
When preparing your manuscript, you will then be able to select this style using the Mendeley plug-ins for Microsoft Word or LibreOffice.
Identify references in the text by Arabic numerals set as superscript. Type the reference list double-spaced, on pages separate from and following the text, with each reference numbered consecutively in the order in which it is mentioned in the text. (References cited in tables and figures, but not in the text, should also be numbered following the text references.) Personal communications, manuscripts in preparation, and other unpublished data should not be cited in the reference list but may be mentioned in the text in parentheses. Identify abstracts with the abbreviation "Abst" and letters to the editor by "Lett" in parentheses; in general, abstracts should not be cited if more than two years old.
List all authors if six or less; otherwise list first three and add "et al." Do not use periods after authors' initials. Kohl P, Day K, Noble D. Cellular mechanisms of cardiac mechano-electric feedback in a mathematical model. Can J Cardiol 1998;14:111-9.

The author(s) should verify that all video clips take less than one minute to load and that they play properly. The file size should be less than 1.5 MB. Larger clips are permissible with 3-D images.
The journal encourages authors to create an AudioSlides presentation with their published article. AudioSlides are brief, webinar-style presentations that are shown next to the online article on ScienceDirect. This gives authors the opportunity to summarize their research in their own words and to help readers understand what the paper is about. More information and examples are available. Authors of this journal will automatically receive an invitation e-mail to create an AudioSlides presentation after acceptance of their paper.
Supplementary Material for Online Publication
In cases where information associated with an article is too extensive for publication in the Main Paper (e.g., detailed methods, data sets, additional figures or tables), this content can be included as online-only supplemental information. All supplementary material (other than videos) should be incorporated in a single PDF file at the time of manuscript submission. The materials should amplify the information in the print article and must be called out sequentially in the text (e.g., Supplemental Methods, Supplemental Table S1, Supplemental Figure S1, etc;). Each set of online supplementary information should be numbered beginning with S1, and continuing as S2, S3, etc. Titles and/or legends for each supplementary figure or item should be included within the table or figure so that it appears in the appropriate place in the PDF file. Supplementary material will not be typeset.
This journal encourages and enables you to share data that supports your research publication where appropriate, and enables you to interlink the data with your published articles. Research data refers to the results of observations or experimentation that validate research findings. To facilitate reproducibility and data reuse, this journal also encourages you to share your software, code, models, algorithms, protocols, methods and other useful materials related to the project.
Below are a number of ways in which you can associate data with your article or make a statement about the availability of your data when submitting your manuscript. If you are sharing data in one of these ways, you are encouraged to cite the data in your manuscript and reference list. Please refer to the "References" section for more information about data citation. For more information on depositing, sharing and using research data and other relevant research materials, visit the research data page.Data linking
If you have made your research data available in a data repository, you can link your article directly to the dataset. Elsevier collaborates with a number of repositories to link articles on ScienceDirect with relevant repositories, giving readers access to underlying data that gives them a better understanding of the research described.
There are different ways to link your datasets to your article. When available, you can directly link your dataset to your article by providing the relevant information in the submission system. For more information, visit the database linking page.For supported data repositories a repository banner will automatically appear next to your published article on ScienceDirect.
In addition, you can link to relevant data or entities through identifiers within the text of your manuscript, using the following format: Database: xxxx (e.g., TAIR: AT1G01020; CCDC: 734053; PDB: 1XFN).Mendeley Data
This journal supports Mendeley Data, enabling you to deposit any research data (including raw and processed data, video, code, software, algorithms, protocols, and methods) associated with your manuscript in a free-to-use, open access repository. Before submitting your article, you can deposit the relevant datasets to Mendeley Data. Please include the DOI of the deposited dataset(s) in your main manuscript file. The datasets will be listed and directly accessible to readers next to your published article online.
For more information, visit the Mendeley Data for journals page.Data statement
To foster transparency, we encourage you to state the availability of your data in your submission. This may be a requirement of your funding body or institution. If your data is unavailable to access or unsuitable to post, you will have the opportunity to indicate why during the submission process, for example by stating that the research data is confidential. The statement will appear with your published article on ScienceDirect. For more information, visit the Data Statement page.

Availability of accepted article
This journal makes articles available online as soon as possible after acceptance. This concerns the accepted article (both in HTML and PDF format), which has not yet been copyedited, typeset or proofread. A Digital Object Identifier (DOI) is allocated, thereby making it fully citable and searchable by title, author name(s) and the full text. The article's PDF also carries a disclaimer stating that it is an unedited article. Subsequent production stages will simply replace this version.
One set of page proofs (as PDF files) will be sent by e-mail to the corresponding author (if we do not have an e-mail address then paper proofs will be sent by post) or, a link will be provided in the e-mail so that authors can download the files themselves. Elsevier now provides authors with PDF proofs which can be annotated; for this you will need to download the free Adobe Reader, version 9 (or higher). Instructions on how to annotate PDF files will accompany the proofs (also given online). The exact system requirements are given at the Adobe site.
If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return them to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and scan the pages and return via e-mail. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures. Significant changes to the article as accepted for publication will only be considered at this stage with permission from the Editor. We will do everything possible to get your article published quickly and accurately. It is important to ensure that all corrections are sent back to us in one communication: please check carefully before replying, as inclusion of any subsequent corrections cannot be guaranteed. Proofreading is solely your responsibility.
A reprint order form will be sent to the corresponding author when the article is accepted and submitted to the publisher.
