Daniel E. O'Sullivan (Ed.)
Chess in the Middle Ages and Early Modern Age
Published by Walter de Gruyter,
Price 89.95 € / $126.00
The page of the publisher provides some more information (table of contents; short excerpts from the book, i.e. the chapters’ first pages), and Mark Donlan recommends the book in his review, see ChessCafe: Scholars' Mate.
I cannot estimate if the content of the book justifies its quite high price...
