A thumbs-up for this service, which eliminates the is-it-or-isn’t-it question on copyright. A big thumbs-down, though, for copyright itself. I checked four books – all more than 70 years old – and every one of them has had the copyright renewed. My longing to see Don Marquis’ delightful Archy and Mehitabel series on Project Gutenberg is thwarted yet again.
