Recent studies have compared the coverage of topical bibliographic databases with Google Scholar. Overlap in coverage ranges from less than ten percent to over ninety percent; coverage by age of material varied greatly as well. A 2006 article by Neuhaus, et al. reported that overlap between Google Scholar and GeoRef was twenty-six percent and that there was a pronounced bias toward English language publications. This study looks more closely at the overlap between these two resources, with specific attention paid to overlap by language and date of publication.
