I found this site of old magazines: National Geographic's,
Scientific American, Technology Review, Popular Electronics, Popular
Science, Modern Mechanix, Mechanix Illustrated, and a few semi-smut
magazines
Dates range from 1910-1980 or so, some 300 total
Not every issue of every mag - some aren't well represented. But the
neat thing is the pages are copied for reading.
