Here’s a pretty amazing web site for anyone with any interest in old, geek-friendly book covers.

Book Worship celebrates “graphically interesting” books from the 1950s, 1960s and 1970s, covering quite a lot of subjects including physics, sci-fi, maths, philosophy and fiction.

If you like the distinctively retro look you only seem to get on old reference books, this is the site to browse. The author says that he’s read most of the books displayed here, which were often “lucky finds” in tucked away bookstores.
