new: a brand new book

used : a used book, which are all in fairly good if not excellent condition

remainder: a brand new book that was sold at a discount
These are books which, in a previous life, were on the shelves at chain and independent bookstores around the world. The bookstore operators needed to make space for new stock, so they sent these titles back to the publishers. When thousands of bookstores do this simultaneously, the publishers have a problem -- they don't have room for all those returns.
(from BookCloseOuts.com FAQ)

sale: or markdown: new books that have been discounted beacuse it was had so long or have incurred some minor wear and tear from physical browsing

hurt: which are new books sold at a discount because they could not be sold as new. These books are usually in excellent condition but may have a dent or small gouge in the cover-- still eminently readable!

short discount(sd): Short Discount books are generally books printed for professional use, dealing with specialized fields of knowledge. Smaller numbers of these books are printed, so the usual discount afforded to independent booksellers is smaller than usual. Hence, these books are usually a little more expensive than other new books.


Binding
Mass Market: A smaller paperback, the size you often find at grocery store.
Trade Paperback: Usually taller, wider, and printed on nicer paper than a mass market.
