In pretty good used condition, a few dings on the back cover. Spine is right & tight, no torn or missing pages that I can see. Doesn’t appear to have any writing in it—no classmate signatures, etc. Fully indexed, & listing photos include all index pages. See other listings for 1965 & 1966 editions. 

I'm happy to combine shipping, but a single book can ship Media Mail, which is FAR cheaper than First Class or Priority.  Considering how heavy these books are, combining shipping (and losing Media Mail eligibility) would probably cost more, not less.  However, if you buy more than one book, I will give you a price break on the books themselves.  

Thanks!
