I just picked upp the 2d Edition "The C Programming Language" (K&R) and the matching "The C Answer Book" combined for about $12 at Alibris. Both books are marked "Circulation of this edition outside the Indian subcontinent is UNAUTHORIZED"
So how come the same publisher, Prentice Hall, can publish the book, written in the US, for the Indian market and sell it dirt cheap while charging me full price ($93) at Amazon) in the US?
The first edition is still a fine book. It just doesn't fully comply with 'ANSI C'.
Ultimately, both books came from Bookloads in Santa Clara. Apparently, they have more...
The nice thing about K&R is that their examples have real value. I use their string functions in every embedded project I create.
