I'll provide a list of textbook ISBN numbers (around 6500). You harvest from [url removed, login to view] the format of the book (hardcover/paperback/etc.), the number of pages, and the dimensions of the book, all of which will be on the Amazon html page for the book (and may well be on their XML server). You can put the output in a regular excel file. I don't care what programming tools you use to do the project.
