Here is some more Free reading for you. Thought @Punkster would really get into this as well as several others.
Warning: In keeping with the niche that pulp magazines occupied, some of the covers or content might not be safe for work or children.
"Pulp magazines (also called Pulp Fiction) were published from 1896 through the 1950’s. The Pulp Magazine Archive has digitized 11,120 pulp magazines that can be read online and is made available by the Internet Archive, a non-profit library of millions of free books, movies, software, music, websites, and more.
There’s a wide variety of titles including Weird Tales, Worlds of IF Science Fiction, True Detective, Witchcraft and Sorcery, Captain Billy’s Whiz Bang, True Story, Adventure, and several more… The science fiction titles are fine, and you’ll find tales by Isaac Asimov, Poul Anderson, Arthur C. Clarke, H. G. Wells, Theodore Sturgeon, Fritz Leiber, Larry Niven, Orson Scott Card, Clifford D. Simak and more. Other titles have differing levels of content."
I remember reading some of these as a child. They blew my mind…Especially the covers.
