Mark's discovery of a mistitled Google Books entry—a book on experimental theater filed as a 2009 book on management—is entertaining but not that unusual. Like the other metadata mixups at Google books (involving authorship, genre classification and publication date, among other things) that I enumerated in a 2009 post "Google Books: A Metadata Train Wreck," there are probably thousands of cases in which the metadata for one book is associated with an entirely different work. Or at least that's what induction suggests; Paul Duguid and I have happened on quite a number of these, some as inadvertantly comical as Mark's example. Clicking on the entry for a book called Tudor Historical Thought turns up the text of a book on tattoo culture, the entry for an 1832 work on the question of whether the clergy of the Church of England can receive tithes turns up a work by Trotzky, the entry for Last Year at Marienbad turns up the text of Sam Pickering's Letters to a Teacher, and so on (see more examples below the fold). What's particularly interesting about Mark's example, though, is that the work is similarly misidentified on Amazon and Abe Books, which indicates that for many modern titles, at least, the error is likely due not to "some (perhaps algorithmic) drudge on the Google assembly line," as Mark suggests, but to one of the third-party offshore cataloguers on which Google and others rely for their metadata.
