What is Web of Science?

Web of Science (WoS) offers access to scholarly literature in all fields of science. The UL subscribes to the following databases:

- Science Citation Index Expanded from 1975
- Social Sciences Citation Index from 1975
- Arts & Humanities Citation Index from 1975
- Conference Proceedings Citation Index- Science (CPCI-S) - from 1991
- Conference Proceedings Citation Index- Social Science & Humanities (CPCI-SSH) - from 1991

The WoS databases contain bibliographic information on articles dating from 1975 from about 9,500 learned journals. Bibliographic means that presented data on an article include title, author, journal in which it was published (the source), volume number, pages, year of publication, and an abstract. Keywords,  which are searchable in the database, have been added to the article.More and more articles are made available as full-text.

Bibliographic information on about 25,000 articles is added weekly to the databases. There is a one- to two-week delay between when the article is published and when it is recorded in WoS. The UL does not subscribe to the so-called 'backfiles' that date back to 1900.

The major difference from other bibliographic databases is that WoS includes the references that come with each journal article and shows how often and by whom an article is cited.
