An assessment of Google Books' metadata
This article reports on a study of error rates found in the metadata records of texts scanned by the Google Books digitization project. A review of the author, title, publisher, and publication year metadata elements for 400 randomly selected Google Books records were undertaken. The results show 36% of sampled books in the digitization project contained metadata errors. This error rate is higher than one would expect to find in a typical library online catalog.
