The digital library contains the fulltext of or references to ACM (Association for Computing Machinery) publications: journal articles, articles in newsletters and conference proceedings, from 1954 onwards.
Within the ACM Digital Library, you can also consult the ACM Guide to Computing Literature, a database with over two million bibliographic records, as well as abstracts of publications from ACM and other publishers.
Coverage: 1954 - present

In Google Scholar, you can find references to academic publications in many different disciplines and forms (e.g. journal articles and preprints). A lot of these publications are available freely online.
Citation data of the publication (who cites who in Google Scholar) can be found at 'Cited by'.

An electronic database, in which reviews, abstracts and bibliographical information about mathematical literature can be accessed. Most of the articles are part of the Mathematics Subject Classification which makes them easy to find in the 'tree-like' structure, in which all subjects are sub-divided. A staff of mathematical professionals has selected expert reviewers for Mathematical Reviews (MR), which first appeared in 1940. Each year they assess the new articles that are added to the database.
Coverage: 1940 - present

The Web of Science by Clarivate Analytics contains references of international journal articles from all scientific disciplines.
It includes data from eight citation indexes:
- Science Citation Index Expanded
- Social Sciences Citation Index
- Arts and Humanities Citation Index
- Conference Proceedings Citation Index - Science (CPCI-S)
- Conference Proceedings Citation Index - Social Science & Humanities (CPCI-SSH)
- Book Citation Index - Science (BKCI-S)
- Book Citation Index - Social Science & Humanities (BKCI-SSH)
- Emerging Sources Citation Index
Chemical indexes:
- Current Chemical Reactions (CCR-EXPANDED)
- Index Chemicus (IC)
Citation indexes offer a unique search method to find later-published journal articles, in which a publication is cited.
