Against Method: Outline of an Anarchistic Theory of Knowledge, by Paul K. Feyerabend
I'd like to get this book in Logos though it's not specifically related to Bible study. It's a significant book on the philosophy of science and the nature of the scientific method (on which Logos already has books, though most of them are specifically about the creation/evolution debate). It's not currently available in any ebook format so it would be a coup for Logos to get it.
