This was a bumper year for records of previously unrecorded Blake publications. The total is a multiple of the discoveries in any previous year. Much of this wealth derives from WorldCat, now for the first time systematically mined for Blake. WorldCat is an extraordinary Tom Tiddler’s ground of silver and fool’s gold. On 11 December 2012 it listed 25,195 entries for William Blake. I looked at the first 5,000, which is one reason why there are so many ephemeral works in the present checklist. Many of the newly recorded works here are in periodicals that I rarely search in—indeed that I had never heard of—such as Classification Quarterly, Francis W. Parker School Year Book, Psychological Medicine, and Victoriographics.
