Scopus is Elsevier’s abstract and citation database launched in 2004. In 2009, the Content Selection and Advisory Board (CSAB) was formed to develop an objective system of evaluation and validation of peer-reviewed journals for inclusion or exclusion in Scopus against transparent and fair criteria. Scopus covers nearly 36,377 titles (22,794 active titles and 13,583 Inactive titles) from approximately 11,678 publishers, of which 34,346 are peer-reviewed journals in top-level subject fields Life Sciences, Social Sciences, Physical Sciences and Health Sciences. It covers three types of sources: Book Series, Journals, and Trade Journals. All journals covered in the Scopus database, regardless of who they are published under, are reviewed each year to ensure high-quality standards are maintained. Searches in Scopus also incorporate searches of patent databases.[1] Scopus gives four types of quality measure for each title; those are h-Index, CiteScore, SJR (SCImago Journal Rank) and SNIP (Source Normalized Impact per Paper). Anyone can find all included journals on the SCImago Journal Rank website.[2] According to the Scimago Journal Rankings, Nature has the highest h-index (1011 as of 2016), and CA - A Cancer Journal for Clinicians[3] has the highest SJR (39.285 as of 2016) and CiteScore 2016 (89.23 in the 99th percentile). Scimagojr.com used to give country ranking based on Total Published Documents, Citable documents, Citations, Self-Citations, Citations per Document and h-index.[citation needed] As per this website USA (h-index : 1965) is in first place, UK (h-index : 1213) is in the second place and Germany (h-index : 1059) is in third place based on national h-index.[citation needed]

Overview

Since Elsevier is the owner of Scopus and is also one of the main international publishers of scientific journals, an independent and international Scopus Content Selection and Advisory Board was established to prevent a potential conflict of interest in the choice of journals to be included in the database and to maintain an open and transparent content coverage policy, regardless of publisher.[4] The board consists of scientists and subject librarians.

Evaluating ease of use and coverage of Scopus and the Web of Science (WOS), a 2006 study concluded that "Scopus is easy to navigate, even for the novice user. ... The ability to search both forward and backward from a particular citation would be very helpful to the researcher. The multidisciplinary aspect allows the researcher to easily search outside of his discipline" and "One advantage of WOS over Scopus is the depth of coverage, with the full WOS database going back to 1945 and Scopus going back to 1966. However, Scopus and WOS complement each other as neither resource is all inclusive."[5]

Scopus also offers author profiles which cover affiliations, number of publications and their bibliographic data, references, and details on the number of citations each published document has received. It has alerting features that allows registered users to track changes to a profile and a facility to calculate authors' h-index. In 2016, a free website, Scopus CiteScore,[6] was introduced. It provides citation data for all 22,500 active titles such as journals, conference proceedings and books in Scopus and provides an alternative to the impact factor.

Scopus IDs for individual authors can be integrated with the non-proprietary digital identifier ORCID.[7]
