While Scopus and Web of Science cover the spectrum of research disciplines, some disciplines also maintain their own citation indexes which do the same citation analysis but with a narrowerfocus.
If you work primarily in any of the disciplines listed below, we recommend getting to know the relevant citation index as well as the more general ones. Some of these can also be found on the A-Z list of databases (log into Okta if prompted).
PubMed, a service of the National Library of Medicine, is an open access database of citations and abstracts for biomedical literature from MEDLINE, the premier database of the National Library of Medicine, and additional life science journals.
SciFinder-n from the American Chemical Society's Chemical Abstracts Service, is a portal for chemistry and chemistry-related information and research, providing access to chemical substances, sequences, and reactions as well as scholarly journal and patent references.First-time users need to register: Register here.
