I just read an article in the recent PCWorld where they were recommending outstanding websites.
Librophile.com
A quick summary of their evaluation.
Offers a massive library free…from classics to sci-fi to fairly recent fiction..while the site itself is hideous, the selection is immense…you can download a book as a zipped set of MP 3 files or subscribe to its chapters on an iTunes RSS feed.
In addition to the free, they sell a wide assortment of premium books starting as low as $7
(Im not quite sure whether the “hideous” refers to aesthetics of design or navigation) but it aroused my interest.
This is in the June edition of the mag and the article lists 52 “incredibly useful sites” and from the others on the list I’ve checked, I would assume that this reco is of as high a quality as the rest.
