Thanks Julie and Carol. Carol, in your original paper on the integration of Embase into CENTRAL (Lefebvre C, Eisinga A, McDonald S, Paul N. Enhancing access to reports of randomized trials published world-wide--the contribution of EMBASE records to the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library. Emerg Themes Epidemiol. 2008 Sep 30;5:13), you reported that your team hand-searched the citations from Embase to identify randomized controlled trials and controlled clinical trials for inclusion in CENTRAL. Therefore, my question relates to whether or not this practice has continued or whether a search was done in Medline (or Embase) and imported into CENTRAL without any further scrutiny, retagging or rejection of tags placed by the original tagging agency. I see the pros and cons of both approaches and am interested in understanding this process further. Thanks again.

Other records on the Cochrane Library may have no indexing, author supplied indexing or indexing from another controlled vocabulary, depending on their origin. This variety of indexing within CENTRAL means that searches need to be equally varied (sensitive) to capture different vocabularies which may be in play.

Even so, I am not sure how this process is done in other major database (e.g. Embase, CINAHL, etc.). Even the Cochrane Library, which gets the majority of its citations from Medline and Embase, doesn't clearly define how the process occurs. I have found a few publications on the development of Cochrane CENTRAL but do actual 'real-time' information. Does anyone know the general process of this occurs? Do screeners actually look at full-texts for publications? For publications where it is not clear from the title/ abstract/ journal-defined key words? For none at all, and all decisions are made on the bibliographic information submitted by the journals. Thanks in advance for thoughts anyone would like to share (it could be personal information that is not documented). Best wishes, Ahmed
