scifi - clean, classic, 50's 60's type suggestions
Looking for classic 50's and 60's "type" scifi... Years ago I read most Heinlein, Clarke, etc. and I would re-read but I'm looking for free and cheap in eBook format. Here's my requirements:
1) No vulgarity
2) No weird religious themes
3) Just a good sci-fi story with no "agenda"
4) eBook (mobi, epub, pdf)
5) cheap, free, or public domain
Would read "modern" stuff but most won't fit into my first 3 points above. In line with #4 & #5 the source would be appreciated.
What say ye?
