Scopus is a scientific abstract and citation database, launched by the academic publisher Elsevier as a competitor to older Web of Science in 2004. [1] An ensuing competition between the two databases has been characterized as "intense" and is considered to significantly benefit their users in terms of continuous improvent in coverage, search/analysis capabilities, but not in price.
Such services typically provide access to full text and full-text search, but also metadata about items for which no full text is available. This list focuses on general-purpose services; OpenDOAR can be used to find thousands of open-access repositories. The table is sorted by the number of works for which full-text is made available.
As of their 2022 list, Clarivate uses "performance statistics" from data in the Web of Science.There are 21 specific fields, and one for interdisciplinary science—Clarivate creates a list of papers that are in the top 1% most highly cited in their field, [a] and admission to the HCR list is based on an author's number of papers in the top 1%.

Correlating Libcitations and Citations in the Humanities with WorldCat and Scopus Data. In A. A. Salah, Y. Tonta, A. A. Akdag Salah, C. Sugimoto, & U. Al (Eds.), Proceedings of the 15th International Society for Scientometrics and Informetrics (ISSI), Istanbul, Turkey, 29 June to 4 July 2015.
The same is true for more comprehensive databases such as Ulrich's Web which lists as many as 70,000 journals, [22] while Scopus has fewer than 50% of these, and WoS has fewer than 25%. [12] While Scopus is larger and geographically broader than WoS, it still only covers a fraction of journal publishing outside North America and Europe.
Moreover, search terms generate related information across categories. Acceptable content for Web of Science is determined by an evaluation and selection process based on the following criteria: impact, influence, timeliness, peer review, and geographic representation. [8] Web of Science employs various search and analysis capabilities.
The Chemistry Citation Index was first introduced by Eugene Garfield, a chemist by training. His original "search examples were based on [his] experience as a chemist". [17] In 1992, an electronic and print form of the index was derived from a core of 330 chemistry journals, within which all areas were covered.
