Who uses The Cochrane Library?
• Who has access to The Cochrane Library ?
• Who has used The Cochrane Library?
• Who uses it regularly (weekly)?
Use of The Cochrane Library
• Usage estimates for 2009:
• a search of CLIB every 1 second • an abstract viewed every 2 seconds• a full text review downloaded every 3 seconds
(across all web platforms, including Wiley InterScience, cochrane.org, La Bibliotheca Cochrane Plus, Bireme, OVID and EBSCO)
The Cochrane Library: an overview • Cochrane Database of Systematic Reviews
– (CDSR; Cochrane Reviews) 4,621• Database of Abstracts of Reviews of Effects
– (DARE; Other Reviews) 14,602• Cochrane Central Register of Controlled Trials
– (CENTRAL; Clinical Trials) 645,086• Cochrane Methodology Register
– (CMR; Methods Studies) 14,604• Health Technology Assessment Database
– (HTA; Technology Assessments) 9,965• NHS Economic Evaluation Database
– (NHSEED; Economic Evaluations) 29,570• About The Cochrane Collaboration (Cochrane Groups) 81

Who produces it?
• The Cochrane Collaboration
52 clinically-focussed Review Groups
e.g. HIV/AIDS, prostate urologic cancers
14 national/regional Centres
e.g. UKCC, USCC
12 Fields
e.g. Complementary Medicine
15 Methods Groups
e.g. Information Retrieval
Who publishes it?
• Wiley-Blackwell

Cochrane Database of Systematic Reviews (CDSR)
4,621 full reviews –

2,020 protocols –
reviews in preparation
(CLIB – 15 May 2011)
What is special about CDSR?
• up-to-date systematic reviews of existing evidence
• higher quality than other systematic reviews (but …)
• reviews updated with new studies / improved methods
• amended / updated from comments and criticisms– pre- and post-publication
What is new about CDSR?
• From January 2010 CDSR is updated monthly online (not quarterly)
(The DVD continues to be published quarterly)
• Other databases continue to be updated quarterly except About The Cochrane Collaboration / “Cochrane Groups” (monthly)
What is new about CDSR?
Diagnostic test accuracy reviews (4)
Diagnostic Test Accuracy Working Group, DTA Regional Support Units and DTA Editorial Team web site and links to DTA reviews

What is new about CDSR?
Overviews of reviews (10)
e.g. Biologics for rheumatoid arthritis: an overview of Cochrane reviews
Consumer-oriented interventions for evidence-based prescribing and medicine use: an overview of Cochrane reviews
Open, small-incision, or laparoscopic cholecystectomy for patients with symptomatic cholecystolithiasis. An overview of Cochrane Hepato-Biliary Group reviews

World no tobacco day (31 May)
What is new about CDSR?
• The Cochrane Collaboration’s Evidence Aid project:
• established Dec 2004 (Indian Ocean tsunami)
• provides reliable, up-to-date evidence from Cochrane Reviews and other systematic reviews
• interventions for natural disasters / major healthcare emergencies
• which interventions work / don’t work / need more research / might be harmful
• provides information to agencies planning for / responding to disasters
What is new about CDSR?
• Evidence Aid (cont):
• Wiley-Blackwell / The Cochrane Collaboration / Evidence Aid opened free, one-click access to the whole contents of The Cochrane Library to everyone in Japan on the day of the earthquake / tsunami (11 March 2011)
• Information translated into Japanese
What is new about CDSR?
• Impact factor for CDSR for 2009 = 5.653
• ranked 11th in the ‘Medicine, General & Internal’ category out of the 132 journals included in the ISI Medicine, General and Internal journal list
(previously 12th)
CENTRAL – clinical trials register in CLIB
• c. 650,000 reports of RCTs and other controlled trials
– 350,000 from MEDLINE(all records indexed as RCT or CCT in PT in humans)
– 100,000 additional reports of trials from searching EMBASE
– 200,000 reports of trials from handsearching journals / conference abstracts
(CLIB – 15 May 2011)
What is special about CENTRAL?
• unique!
• best single source of reports of randomized controlled trials
• ‘trials on a plate’
What is new about CENTRAL?
• In October 2009 Metaxis awarded contract to build a new Cochrane Register of Studies (CRS)
– to feed into CENTRAL
Due for release internally late 2011
CRS will be study-based and reference-based –
as will CENTRAL
