ICT paperback is out!

The revised/corrected third edition of Introducing Category Theory is now available as a paperback. To keep the cost minimal, this is again via print-on-demand from Amazon US, Amazon UK, and of course other Amazons too, with ISBN 1068346728.

There are many corrections of typos, and quite a few minor expositional improvements. Is it worth getting the new paperback if you already have the January printing of the third edition? Well why not? It is only the cost of three cappuccinos … And, for many of us, a physical book is so much easier to work with than a very long PDF. Treat yourself!

A hardback for libraries (and for Amazon refuseniks) should become available on June 1st: more details to follow.
