To keep track of what's happening in your research world, turn to Scopus. Across all research fields—science, mathematics, engineering, technology, health and medicine, social sciences, and arts and humanities—Scopus delivers a broad overview of global, interdisciplinary scientific information that researchers, teachers and students need to stay informed.
Comprehensive: Scopus has the largest breadth and depth when compared to any other A&I database in the world. Timely updates from thousands of peer-reviewed journals, preliminary findings from millions of conference papers, and the thorough analysis in an expanding collection of books ensure you have the most up-to-date and highest quality interdisciplinary content available. Content indexed in Scopus is coming from 5,000 publishers from around the world.
Frequently updated: Never miss out on what's new in your field. Scopus is the only leading database that is updated daily rather than just weekly.
Unbiased: You can rely on our independent and expert content selection & advisory board (CSAB) who use strict criteria to vet the sources that Scopus includes. Learn more about our current board and content selection methods.
Reliable: By focusing on the world of research, you can trust that your Scopus search results will be accurate and relevant, and delivered to you quickly so you can spend less time searching and more time reading.
What content is included in Scopus?
More than 66 million records in Scopus, which includes:
- Over 22,748 peer-reviewed journals, of which more than 3,476 are full open access (see the Scopus Source List)
- Over 320 trade journals which reach a specific industry, trade or type of business have been selected by the CSAB for Scopus coverage. These journals are seldom refereed and do not always have an editorial board. Scientifically relevant articles are selected from trade journals for Scopus coverage if they meet the following criteria:
- Minimum of one page
- Minimum of one mentioned author
- Articles-in-press (i.e., articles that have been accepted for publication) from more than 5,000 publishers, including Cambridge University Press, the Institute of Electrical and Electronics Engineers (IEEE), Springer-Nature, Wiley-Blackwell and, of course, Elsevier
- For an overview of titles that are discontinued from Scopus coverage due to quality issues see the Scopus Discontinued Sources List
Over 558 book serials are covered in Scopus, accounting for 34,000 individual book volumes and 1.3 million items
More than 138,000 non-serial books (see the book title list), available in Scopus and 20,000 added each year.
- Subject areas: Focus on Social Sciences and Arts & Humanities, but also includes Science, Technology & Medicine (STM)
- Coverage years: Back to 2005 (2003 for A&H)
- Book types: Monographs, edited volumes, major reference works, and graduate level text books
- Publishers can proactively suggest their book forward flow for Scopus indexing via the Scopus Book Suggestion Form
7.7 Million conference papers from over 97,100 worldwide events, containing:
- High energy physics from the inSPIRE database
- Computer science conferences and workshops from DBLP Computer Science Bibliography
- Society meetings including the IEEE, American Chemical Society (ACS), Association for Computing Machinery (ACM), Society of Petroleum Engineers (SPE), The Minerals, Metals & Materials Society (TMS), American Geophysical Union (AGU), European Society of Cardiology (ESC), International Society for Chemotherapy (ISC), American Society for Information Security (ASIS), Japan Society of Mechanical Engineers (JSME), and many more
- Conference paper selection is done based on the relevancy and quality of the conference in relation to the subject field. Priority is given to conference materials published by reputable organizations and publishers in relevant subject fields. Scopus does not consider individual conference material suggestions to be included in the database. Serial conference titles that have a registered ISSN can be suggested for Scopus coverage via the above mentioned title evaluation process.
Journal selection criteria
To be considered for review, all journal titles should meet all of these minimum criteria:
- Consist of peer-reviewed content and have a publicly available description of the peer review process
- Be published on a regular basis and have an International Standard Serial Number (ISSN) as registered with the ISSN International Centre
- Should in general have a 2 year publication history
- Have content that is relevant for and readable by an international audience, meaning: have references in Roman script and have English language abstracts and titles
- Have a publicly available publication ethics and publication malpractice statement
CSAB members have deep subject matter expertise, and are committed to actively seeking out and selecting literature that meets the needs and standards of the research community that they represent. Journals eligible for review by the CSAB will be evaluated on the following criteria in five categories:
28 Million Patents from five patent offices:
- US Patent & Trademark Office
- European Patent Office
- Japan Patent Office
- World Intellectual Property Organization
- UK Intellectual Property Office
Many content types—journals, conference proceedings and books— contribute, through citation activity, to the overall evaluation of scholarly research and therefore, should be included in Scopus. While journals and conference proceedings are usually associated with timely dissemination of scholarly information, books typically provide a more thorough analysis of a specific (or broad) topic. By having books included in Scopus, we continue to connect the citation patterns of journals, conference proceedings and book content. This is achieved through:
- Improve: Research within Arts & Humanities and Social Sciences is frequently published in books rather than journals. By including books in Scopus these subject fields become more complete, as do the author profiles and h-index of researchers working in the A&H and Social Sciences.
- Enhance: Simply by having the books content in Scopus, makes them more discoverable.
- Measure: Because books often cite journals, having books included in Scopus makes the citation counts of journals more accurate. And, we are able to further measure the impact of those books.
- Increase: For research assessment, the addition of books gives researchers within the A&H the opportunity to better show their full scientific output in their Author Profiles.
Open Access Journals
Out of the 21,500+ active journals indexed in Scopus, more than 3,400 are listed as open access (OA). In Scopus, journals are identified as OA if they are registered with either the Directory of Open Access Journals or the Directory of Open Access Scholarly Resources, and are the following OA journal types:
- Gold OA & Gold (waived) Journals: Journals in which an Article Processing Charge (APC) has been paid and all articles are available online without any restrictions
- Subsidized Journals: Journals which do not charge an APC, but instead are subsidized by other means (including university, government, agency, corporate sponsorship, print subscriptions, and advertising)
Note that, in Scopus, OA is only recognized at the journal level and not at the article level, which means the following journal types are not identified in Scopus as OA:
- Hybrid OA Journals: Subscription-based journals that offer an APC-based OA option
- Delayed Hybrid OA Journals: Subscription-based journals which provide free online access upon the expiry of an embargo period, following the initial article publication date
- Subscription Journals: Journals which cover publication costs through access tolls such as subscription costs
To see the full list of OA journals in Scopus, download the Scopus Source List and filter column Q: ‘Open Access status,’ by OA status. Note: the Scopus title list is updated three to four times per year which may result in minor and temporary discrepancies in a journal’s OA status. You can also browse Scopus’ OA journals via the Browse Sources tab on Scopus.com.
