Hi,

I'm purchasing as many used books for my son as I can.  I have found one that is stated as being a NASTA version.  Could anyone explain what that means and whether the book is different than any other versions.  I also see many Instructors versions of the textbooks out there for sale, are they generally allowed to be used?  I am also seeing International versions which are usually paperback vs the U.S. Hardbound version, again are there any differences I should be concerned about?

Thank You,

Teena

I found this acronym for NASTA

NASTA National Association of State Textbook Administrators

Doesn't look like there should be any difference, but here are a couple more links you can look at about NASTA.

I realize this post is old, International editions are paperback and the cover design is different but the pages match exactly and nothings different at all, I've used them and its a great way to save money, I do realize again this post is old, but Im hoping this is useful to someone.
