Query: Field Guide to Pattern Glass

This is probably as easy-to-use as such an EAPG guide can be, given the vastness of the subject. The line drawings are clear and give a better sense of pattern than most photographs. I liked the way it was organized into pattern categories (Diamonds, Facets, Ribs and Columns, etc.), but found the amount of information about specific patterns varied widely. In my first attempt at using the Index, I discovered a mistake in the page number for "Jasper" (p. 156, not p. 158), but have generally been glad I added this paperback to my library.
