I am pleased to report that my book Practical Foundations of Mathematics Cambridge Studies in Advanced Mathematics 59 Cambridge University Press, 1999 ISBM 0 521 63107 6 has sold enough copies (not too sure how many that is) to warrant a reprint. I have been asked to send any [minor] corrections by 18 August, which is really rather short notice. If you have any notes of spelling mistakes, broken sentences, wrong firstnames, wrong fonts or whatever, please send them to me as soon as possible. Obviously I also want to know if there are mathematical errors, but it will probably only be possible to change a small amount of text on this occasion. (However, judging by the experience with "Proofs and Types", it is likely to be another ten years before I get the opportunity to make substantial changes.) The full text of the narrative of the book (with only the simplest parts of the mathematics) is available on the web in HTML at http://www.dcs.qmw.ac.uk/~pt/Practical_Foundations Some of you got your copies by a special arrangement with Richard Knott at CUP in March last year. I heard some rumours that not all of the orders that were made in that way were actually fulfilled. If you sent an order to Richard but didn't get your copy, please tell me. Paul Taylor
