I have a book "The C Programming Language" by Kernighan and Ritchie. It's quite a famous book in programming circles. I got it in 1989 but the most recent copyright is 1978. It doesn't say "first edition" and there is no other edition indicator, nor can I find if this edition was reprinted at a certain time other than 1978.
It even says it was typeset under unix running on a PDP-11/70 (a very old computer).
So
- How do I know if this edition is a reprint of the 1978 edition?
- How do I know if I have a first edition book?
I don't know what this page is called, but here's all the publishing info:
A bigger version as PNG.
Thank you.
