Stay abreast of the research happening in your area
When searching for insights, efficiency is a priority. Being able to search a single, trustworthy and authoritative database saves valuable time that would otherwise be spent cross-checking multiple databases and having to confirm results.
Since Scopus delivers the broadest overview of global, interdisciplinary scientific data and literature, across all research fields, researchers know that the odds of missing key research information are greatly reduced.
Get started with Scopus.
Unparalleled and continuous access to critical research output from around the world
Researchers trust the information and data they discover with Scopus because the content on Scopus comes from over 7,000 publishers that must be reviewed and selected by an independent Content Selection and Advisory Board (CSAB) to be, and continue to be, indexed on Scopus.

Preprints now in Scopus
Scopus incorporates preprints from 2017 and onward as a content type in Author Profiles so users can discover the latest contributions of a researcher.
Scopus content: High quality, historical depth and expert curation
In recent years, Scopus has added over 1.7 billion cited references, dating back to 1970, to complement the database's existing records that date back to 1788 and further increase the depth of content.
Additionally, over 4.5 million articles have been reprocessed to index more cited references on Scopus, adding 7.5 million pre-1996 article abstracts for users to discover.
Why citations matter
With over 1.7 billion cited references now on Scopus, each paper indexed has, on average, 10-15% more citations than our nearest competitor. More cited references mean:
- more extensive bibliometric and historic trend analysis
- more complete author profiles
- improved h-index measures for authors who began publishing prior to 1996

How stringent are our standards?
Every year, approximately 3,500 new titles are suggested for inclusion in Scopus, but only 33% of those titles meet the technical criteria. And of those roughly 1,200 titles, only 50% are accepted after CSAB review.
We're proud of our transparent selection process and independent review board. The international experts on our Content Selection and Advisory Board continually review new titles using both quantitative and qualitative measures. Only serial titles may be suggested to the Content Selection and Advisory Board for inclusion on Scopus. Serials include journals, book series or conference series.
Journals: The bulk of the content on Scopus is peer-reviewed journals which are selected according to our content coverage policy. Any serial publication with an ISSN, that meets the technical criteria can be suggested for review and covered on Scopus. Over 5,500 peer-reviewed titles are full open access titles (according to DOAJ and/or ROAD).
Trade journals: Serial publications covering and intended to reach a specific industry, trade or type of business. These publications usually are a magazine type of periodical with articles on topical subjects, news items and advertisements that appeal to those in the field. Trade journals are seldom refereed and do not always have an editorial board. Abstracts are usually short or nonexistent and few or no references are given. Usually an ISSN is available. Trade journals are included in Scopus because users and librarians consider selected articles to be scientifically relevant. Only articles or reviews of scientific relevance are included in Scopus.
Book series: A serial publication that has an overall series title, an ISSN and in which every volume and/or issue in the series is also a book with an ISBN. Usually, but not always, each book has a book title separate from the series title and a different editor or editors. Typically, each book is a monographic publication. Book series are usually published irregularly.
Books (non-serial titles): A non-serial source is a publication with an ISBN and is usually a monograph or composed work. One-off book publications covered in Scopus includes monographs, edited volumes, major reference works and graduate level textbooks. Over 217,000 book titles are in Scopus that significantly increase the breadth and depth of coverage for book-oriented disciplines in the social sciences and humanities. Books are indexed on both a book and a chapter level. Book selection policy is publisher-based, meaning publishers are reviewed based on the relevancy and quality of their complete books list. Once a publisher is accepted, all books from that publisher that fit the scope of the project are indexed in Scopus.
Conference material: Conference material enters Scopus in two different ways: (1) as a special issue of a regular journal, (2) as a dedicated conference proceeding. Proceedings can be published as serial or non-serial, and may contain either the full articles of the papers presented or only the abstracts. The source title usually includes words like proceeding(s), meeting(s), conference(s), symposium/symposia, seminar(s) or workshop(s) (or their synonyms in other languages), although some journals also include proceeding(s) in the title. Scopus covers conferences that publish full-text papers (i.e., document type conference papers).

Content types included on Scopus are either serial publications that have an ISSN (International Standard Serial Number) such as journals, book series and some conference series, or non-serial publications that have an ISBN (International Standard Book Number) like one-off book publications or one-off conferences.
