Here is the new wildflower book (the images are from 2007, but I just created the book this month). The link below provides a preview of the book. It is a thin little book with 36 wildflower images. (Yes, you can purchase copies here via this link.)
This book is PoD (publish on demand) via Blurb. Specifically, Blurb refers to this 6×9 format as a “trade” book. The paper thickness is “text” weight rather than the heavier paper typically used for photo books. Until this year, Blurb offered the trade format only for black&white books, but they now offer color.
This particular book is 40 pages, meaning 20 double-sided papers. Why? Because Blurb pricing is based on 20-page increments. A book with 22 pages cost the same as 40 pages, but a book with 42 pages would cost a bit more.
