Google Books: A Metadata Train Wreck
Mark has already extensively blogged the Google Books Settlement Conference at Berkeley yesterday, where he and I both spoke on the panel on "quality" — which is to say, how well is Google Books doing this and what if anything will hold their feet to the fire? This is almost certainly the Last Library, after all. There's no Moore's Law for capture, and nobody is ever going to scan most of these books again. So whoever is in charge of the collection a hundred years from now — Google? UNESCO? Wal-Mart? — these are the files that scholars are going to be using then. All of which lends a particular urgency to the concerns about whether Google is doing this right.
My presentation focussed on GB's metadata — a feature absolutely necessary to doing most serious scholarly work with the corpus. It's well and good to use the corpus just for finding information on a topic — entering some key words and barrelling in sideways. (That's what "googling" means, isn't it?) But for scholars looking for a particular edition of Leaves of Grass, say, it doesn't do a lot of good just to enter "I contain multitudes" in the search box and hope for the best. Ditto for someone who wants to look at early-19th century French editions of Le Contrat Social, or to linguists, historians or literary scholars trying to trace the development of words or constructions: Can we observe the way happiness replaced felicity in the seventeenth century, as Keith Thomas suggests? When did "the United States are" start to lose ground to "the United States is"? How did the use of propaganda rise and fall by decade over the course of the twentieth century? And so on for all the questions that have made Google Books such an exciting prospect for all of us wordinistas and wordastri. But to answer those questions you need good metadata. And Google's are a train wreck: a mish-mash wrapped in a muddle wrapped in a mess.
