Latest Events & UPDATES

CENTRAL clean-up – March Issue3 2014 (Published & released to The Cochrane Library  started processing on 31st March 2014)

The records published in the Cochrane Central Register of Controlled Trials (CENTRAL) have undergone a “cleanup”. Metaxis, the company that compiles CENTRAL on behalf of Cochrane and delivers the records to Wiley, ran a series of checks to identify errors and omissions in CENTRAL records and to correct them automatically where possible.  Most records have had at least one field cleaned. Fields that should only contain specific values have also been tidied up (for example the Study Design field should only contain RCT, CCT, ITS or CBA, and the Language field should only contain the ISO language codes). 

An in-depth deduplication check has also taken place which has resulted in 8793 records being merged with other records.

Some examples of the kind of errors fixed are:

  • Fields with clearly incorrect values have been cleared (e.g. MeSH terms in a Year field or Keywords in a URL field)
  • Titles all in upper case (capital letters) have been converted to sentence case
  • Page numbers have been changed to the abbreviated format  (e.g. 687-90 not 687-690)
  • The values in the Study Design field have been restricted to RCT, CCT, ITS and CBA
  • Language field values have been converted to ISO 639 codes (e.g. eng not English)
  • Pubmed IDs checked (some Pubmed IDs were pointing at incorrect Pubmed records)
  • URLs checked for valid structure (e.g. http://www....) and incorrect URLs removed
  • DOI checked for valid structure (e.g. 10.1111/papr.12013) and incorrect DOIs removed
  • Journal names have been converted to NLM journal authority list format (e.g. “Lancet Neurol” converted to “Lancet neurology”)
  • MeSH terms have been checked against the current (2014) thesaurus and errors corrected

A full report will be made available once the project is finalised.

Scheduled Maintenance

NEXT release activity FOR cochrane - COMMENCING FRIDAY 2nd MAY 2014.

Details to follow nearer to the activity date.

If you do have any problems with access please contact  cs-cochrane@wiley.com.

Due to the natural of technology and its development, it has become standard practice throughout many organisations to have regular, scheduled, updates to systems. By taking this approach, there is a reduced risk to functionality and other systems. Users can also plan to avoid usage during these maintenance periods.The dates below indicate an expectation of scheduled maintenance which may disrupt access and functionality of The Cochrane Library.(The standard schedule for developer activities commences at 10am (UK Time), and continue for 2 hours, though this is subject to change).These dates are subject to change.Notifications of the expected downtime will be sent out in the week prior to the expected downtime, to users on the Cochrane 'lists' (TSCs, MEs and Cochrane Library User Group).
