LibraryThing, a major social-networking-through-books site, launched its first iPhone app. Local Books is free and lists bookstores, libraries and book-related events near you.

Features include:

* Search for venues (bookstores and libraries) as well as events near your current location using the iPhone’s built-in location features.
* Search for venues and events at any location or by name.
* Venues can be sorted by distance, name, or type.
* Venues are color coded, following the maps on LibraryThing Local (colors correspond to the colors used on maps in LibraryThing Local).
* Each venue has a detail page with a map. Tap it to jump to the iPhone Maps application.
* Venues often sport a description, clickable website and phone number links, events, and a photo.
* You can favorite locations and events, and there’s a “Favorites” list where you can find them.
