AbstractThe Cochrane Central Register of Controlled Trials (CENTRAL) includes details of published articles taken from bibliographic databases (notably MEDLINE and EMBASE), and other published and unpublished sources. CENTRAL records include the title of the article, information on where it was published (bibliographic details) and, in many cases, a summary of the article. They do not contain the full text of the article. About three-fifths of the records in CENTRAL are taken from MEDLINE. Also, each Cochrane Review Group maintains and updates a collection of controlled trials relevant to its own area of interest, these are called ‘Specialized Registers’. Each Cochrane Review Group may also collect items that are not relevant to its own field of interest; these are known as ‘Handsearch Results’. All Cochrane Review Groups’ Specialized Registers, the handsearch results register, relevant records retrieved from MEDLINE, and relevant records retrieved from EMBASE, are merged as described here and published as CENTRAL. The Publishers, John Wiley & Sons Ltd acknowledges the contribution made by Elsevier to CENTRAL by the provision of EMBASE records (Copyright © 2008 Elsevier B.V., Amsterdam. All Rights Reserved). EMBASE records can be identified by a sole EMBASE ID in the Accession Number field. Wiley also thanks Update Software for the continued use of their data formats in CENTRAL.
