Yesterday the University of Michigan Press sent me a link to their online catalog. Printing and Prophecy is in there, on page 49. And they sent me a link to download my author's copy of the e-book edition. The printed copies are, I assume, in the mail. Amazon still lists the book as not yet released, but they also are now providing an extensive preview, as is Google Books. If it's on Google, it must be for real.
The timeline for writing and publication went something like this:
March: I have the initial idea and start background reading.
May: Humboldt application submitted
October: First conference paper about Lichtenberger
November: Notification of successful grant application
August: Archival research commences
October: Writing begins
May: Alpha draft completed
May: Beta draft completed
June-July: Revisions. At the end of July, I'm ready to start querying.
August: The University of Michigan Press wants to see the full manuscript.
October: Initial reactions are positive.
January: Reader reports come back. They recommend publication.
March: The editorial board agrees, and extends a publication contract.
July 1: I submit the final manuscript.
January: The copy edited manuscript is submitted.
July: Page proofs and index are submitted.
November: Printing and Prophecy appears in print.
I think I can see some ways to make the next book go faster.
