Go to the Library Without Leaving Your House
If you liked learning about fore-edge paintings, you’ll love the New York Public Library’s Tumblr.
And the Smithsonian Libraries’ Tumblr.
And the University of Iowa’s Special Collections & University Archives Tumblr.
And all the other library blogs linked in this MetaFilter post, which upload pictures of all kinds of nifty stuff from their stacks, from “the original American serialized version of Charles Dickens’ Bleak House” to century-old cat postcards.
