This study addresses the discussion of “quality versus coverage” that often arises if a choice is needed between Scopus and Web of Science (WoS). We present a new methodology to detect problems in the quality of indexing procedures. Our preliminary findings indicate the same degree and types of errors in Scopus and WoS. The more serious errors seem to occur in the indexing of cited references, not in the recording of traditional metadata.
