Qualitative aspects of the Bradford distribution

  • J. Pontigo
  • F. W. Lancaster


A study was performed to determine whether the quality of journal articles declines as one moves through successively less productive Bradford zones. Two measures of qualityrate of citation and expert judgement-were used. It was found that articles in the least productive zone were cited significantly less than those in the most productive zone. However, experts did not judge them to be of lesser quality.
