My "Google” was the Worlds Largest Bookstore in downtown Toronto. It had all the great computer magazines you mentioned and tons and tons of computer books. I would buy Dr. Dobbs (DDJ) for C and Turbo Pascal on the IBM PC, Antic and Analog Computing for game programming on the Atari. The book section always had interesting stuff - Mostly I bought Microsoft Press stuff in the 80s and 90s when I was in University.

It always seemed unfair to teenage me that the C$ price was 20-40% more than the USD price.
