A NOTE ON THE BOOK OF HOURS OF CATHERINE OF CLEVES
This site has a very detailed history of its book. It is a book that had a wealthy patron which shows in the book itself. It has links to images with titles.
I would recommend this site if you are looking for specific examples of books of hours rather than general information on them.

These pages are the work of the students enrolled in Art 238, "Art and Medieval Mentalities," taught by Professor Christine Hamza during the Spring Semester, 2003.
