Here are three random library additions, the only common denominator of which was that I picked all of them up at Half Price Books.
Leckie, Ann. Ancillary Justice. Orbit, 2013. First edition trade paperback original, a Fine, new and unready copy. Hugo and Nebula Award winner. Bought for $7.99 at Half Price Books. Supplements the later Gale/Thorndike Press large print hardback edition and the Subterranean Press signed/limited edition.
Pohl, Frederik and Lester Del Rey (as Edson McCann). Preferred Risk. Simon and Schuster, 1955. First edition hardback, a Near Fine- copy with page block spotting at heel, in a Near Fine dust jacket with traces of wear at points and moderate soiling to white rear panel. Inscribed by Pohl: “To Rick—/With all good/wishes—/”Edson”/or/Fred Pohl.” Currey (1979), page 404. Bought for $8, down from $10 with a 20% off coupon. This is a case of knowing more than the bookseller, since I knew this was a Pohl/Del Rey pseudonym and what Pohl’s signature looks like. As for the book itself, evidently Galaxy magazine and Simon and Schuster ran a contest for an SF novel, didn’t like any of the submissions, and got Pohl and Del Rey to write this under a pseudonym for the contest.
Vachess, Andrew, Geoff Darrow, Michael Black and Gary Gianni. The Shaolin Cowboy Adventure Magazine No. 1. Dark Horse, 2012. First edition trade paperback original, a Near Fine+ copy with a small scrape at heel and just a trace of wear. Signed by Vachess, Darrow and Black. Pulp fiction homage that looks like fun. Bought for $7.99.
