Scopus is Elsevier’s abstract and citation database launched in 2004. 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. The complete list is on the SCImago Journal Rank website. Searches in Scopus also incorporate searches of patent databases. 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).

Aims
Various methods have been used to evaluate academic journals and consider for indexing. One gets a picture of how competitive the journal is by looking at the acceptance rate vs the rejection rate. Another way is to examine how often articles are cited in subsequent research to gauge a journal's impact.
Indexation of a journal is considered as reflection of its quality. Indexed journals are considered to be of higher scientific quality as compared to non-indexed journals. Indexing medical and Lifesciences Journals have become a debatable issue. For a long-time Index Medicus has been the most comprehensive index of Medical Science journal articles. Over the years, many other popular indexing services have developed. These include MEDLINE, PubMed, EMBASE, SCOPUS, EBSCO, ProQuest, Gale and Chemical Abstracts Service, Publishing Electronic Databases among others.
Scopus is the largest abstract and citation database of peer-reviewed literature, featuring smart tools to track, analyze and visualize research. Scopus delivers the most comprehensive overview of the world's research output in the fields of science, technology, medicine, social sciences and Arts & Humanities.
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."
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.
