What does CENTRAL include?

CENTRAL is made up of more than 2 million bibliographic records (author, source, year, etc.). Many records include an abstract (a summary of the article). They do not contain the full text of the article.

CENTRAL is created from many trusted sources. Most records come from bibliographic databases (mainly Pubmed and Embase.com). They also come from other published and unpublished sources, including CINAHL, ClinicalTrials.gov and the WHO's International Clinical Trials Registry Platform. Records get included irrespective of language or date of publication.

CENTRAL first began publication in 1996, but its composite nature means that it does not have a start date, like some biomedical databases do.
