title: Five large Chinese biomedical bibliographic databases: accessibility and coverage.
abstract: BACKGROUND
  Much biomedical research is now undertaken in China.
  
  
  METHODS
  Five large biomedical databases originating from China (CBM, CMCC, CNKI, VIP and WANFANG) are described and their utility and accessibility investigated.
  
  
  RESULTS
  These databases index 2500 journals largely not familiar to MEDLINE users. Free access, search features, record selection, ease of downloading and cost of subscription varies considerably between databases.
  
  
  CONCLUSIONS
  Searches in all databases benefit from the use of simplified Chinese and all provide links to full text articles. Less than 6% of the 2500 journals in the five databases were listed as being indexed for MEDLINE.
