Here are three links for your enjoyment.
The first one I just came across this morning and thought the content was fabulous. It is simply a rare book guide from a dealer’s perspective. About a new book every few days from the folks at Any Amount of Books/ London. The site is www.BookRide.com.
Next we have a stupendous library of links on just about everything you can find on books. The Digital Librarian’s Book Collecting and Book History links.
And finally Book Sale Finder. Sign up with these guys and they will send you an email advising of book sales within X kilometers of your place. Look for the link at the top of the page called ‘Sale Mail’.
