title: Searching the Polish Medical Bibliography (Polska Bibliografia Lekarska) for trials.
abstract: BACKGROUND
  The Polish Medical Bibliography (Polska Bibliografia Lekarska) contains 350 000 records dating from 1979. These records from the fields of medicine, nursing, dentistry, health care systems and preclinical sciences are from nearly 300 biomedical journals published in Poland.
  
  
  METHODS
  We systematically searched the Polish Medical Bibliography Part II (1996-2006) CD-ROM (July 2006) using both English and Polish phrases for randomized trials, manually checked results and, for the trials identified in this way, sought these on medline and embase.
  
  
  RESULTS
  Systematic searching identified records of 680 randomized trials from all areas of health care. Nearly 40% of these were not found on either medline or embase.
  
  
  CONCLUSIONS
  The Polish Medical Bibliography should be of interest to health care information specialists concerned with comprehensive searches for trials.
