Love libraries, but hate having to look at all of those dusty old books? Good news: following the recent Seattle-only launch, it's now possible to check out Amazon Kindle books from some 11,000 library sites, as long as you have a valid library card and an Amazon account. You can check a library's inventory (like their physical counterparts, the libraries only have a limited number of Kindle copies for each title) and download copies to your Kindle or Kindle app-enable device via WiFi or USB. Like the libraries' physical books, Kindle copies will carry an expiration date -- but after that time, they can either be renewed or purchase through Amazon, with all of your bookmarks and notations still in place. Press release after the break.
