Dear Joel David Hamkins,

I would like to buy your new book “a mathematicians year in japan”. Unfortunately Amazon will not let me buy, most likely because I’m not in the U.S. Is there any way to get a print copy instead of a kindle version? Barring that is there perhaps another way to obtain a copy? Thanks in advance!

Lee

Dear Lee,

I’m very sorry, but the book is not available in paper format. It currently exists only in electronic format, on Kindle. Kindle format books can be read on almost any device (phone, computer, tablet) with the free Kindle application.

regards,

JDH
