Abstract: Purpose - The purpose of this research is to provide the 
scientific community with some quantitative data of relevance to the 
evaluation of two major citation databases. In addition, various aspects 
of the methodology of database coverage comparisons are discussed.
Design/methodology/approach - Calculations of the overlaps between the 
journal lists of Web of Science and Scopus and some other major scientific 
databases are presented.
Findings - The results provide some measures of the overall title coverage 
as well as the amount of unique material in the sources studied.
Research limitations/implications - The journal title overlap calculations 
are based on journal lists provided by the database producers rather than 
searches in the databases themselves. Any inaccuracies in the lists may be 
reflected in the results. Also, the lists do not provide any information 
about the depth and consistency of the coverage. The nature of possible 
error sources is discussed.
Originality/value - The methodology chosen allows comparatively quick 
comparisons between the contents of databases. This makes it suitable for 
analysis of trends in database coverage.
