Hathi has announced that bookworm and other free tools can now worm merrily across the full-text from all of Hathi’s 16.7-million items. Previously the tools were restricted only to the public domain holdings, but they now also include the locked-down texts.

One can now easily do cool searches, for instance, to discover that 1808 was the year of “peak eldritch” in literary books. And that the arrival of the mass-market browser-based Internet in late 1995 probably caused the “Lovecraft bounce” which began then.
