Sounds like you might mean some of the Julius Schwartz edited DC books like "Strange Adventures," "Mystery in Space," and even books like "Flash" and "Green Lantern."
Back in the fifties a lot of the DC books had crossword puzzles, word puzzles, and so on which I enjoyed a good deal. Naturally, you won't find any DC material here. I do think you will find a bit of that sort of thing in some of the Dell books, a few of the Charltons, and possibly a few titles from Magazine Enterprises, but few example of science oriented material.
