LibraryThing (remember LibraryThing? We had a visit from Tim, back in the day) went live last week with a neat new app: LibraryThing Local. I don't usually Oo and Ah over stuff that's all Web 2.0ey, but this is pretty neat.
It's basically a mapping system which allows LibraryThing members to add "venues": libraries, bookstores, festivals, and other book-related locations and events. For instance, here's all the recently-added venues within five miles of The Library of Congress in Washington, D.C. (zipcode 20540). Thingology has a post with a bunch of other examples.
Users can bookmark their favorite spots, and libraries and bookstores can even officially sponsor the entries for their venues, if they didn't add themselves.
Here's the LibraryThing blog announcement of the new service, and an update after the first 9,000 venues were added.
