How lovely to discover The Art of Penguin Science Fiction (via Likely Stories), for me a trip down memory lane as many of the covers of the books are the very editions I read in my long-gone SF-devouring days. As one might guess, the website explores the history and cover art of science fiction published by Penguin Books from 1935-1977. Further explanation of the project is here; a table of contents of 20 articles (well, 19 and an entr'acte) is here. I'm unlikely to read SF again, but those covers are so nostalgic! Click on each one for a short review of the book itself.
