The books

How buying works. The Buy button opens the book in the printer's own store, which takes the payment, prints the copy and ships it. Until a book is on sale, its button asks to be told the day it is. Instructor books are not sold here: they come with a site licence. How licensing works.

Every price is introductory, subject to counsel. Not issued, approved or endorsed by the New York State Education Department or any school district. Schools decide how to use its reports.
