There are loads of free audio and e-books available online for the taking, but tracking them down across their many sources can be tough. Web-based search tool Librophile makes the job a lot easier.
If you're not sure what books you're looking for, just page through the listings. Each book entry includes the option to open a pop-up window to play an excerpt, opens the e-book in a new browser window, download the file in ZIP format, or subscribe to an audio book in iTunes. Hovering your mouse over the book title pops up a summary of what the story is about.
Librophile also lets users search by keyword or book title, or through categories like Popular or Genre. One particularly great feature of this free website is how easy it is to listen to audio books right in the browser without installing a bunch of software. It's a definite plus for visually impaired users or kids who won't sit still long enough to read the classics in dead-tree form.
