Post of the week - already in the Post of the Week thread!
I have a book called Computability and Unsolvability
by Martin Davis. It was originally published in 1958, but I have the second edition, which was published in 1982 by Dover.
The second edition includes an appendix consisting of an article by Davis, from American Mathematical Monthly
that was published in 1973 following a breakthrough in the subject. The references section of the article is included as part of the appendix. One of the entries in that reference list is Computability and Unsolvability,
by Martin Davis, and he even updated it to include after the original entry (Dover, 1982)
It would be meta enough that I have a book that contains a list of references one entry of which is the book itself. What really kicks it for me, though, is the Library of Congress Cataloging in Publication Data that is printed on the copyright (or title verso) page. The first subject for the book that it gives is ... 'Recursive functions.'
