There was a recent piece about the World eBook Fair in Information Today. The theme of this year's fair is "Own your own library" and more than 1.2 million e-books will be offered for free download by the participating organizations.

For stores that like to provide content to students for free, or are working on initiatives like faculty editions of classics, POD content, or other projects, these links could be useful.
