BookGlutton offers a number of interesting options for ebook aficionados. First, it is a self-contained epub format reader for your browser. It offers a simple, clean, and effective online reading option, similar to what you find on an iPhone or a dedicated ebook reader like the Kindle. A drawback to BookGlutton is that some of its advanced features feel a little rough around the edges. For example, the font sizing button cycles through fonts sizes, each time repaginating the ebook.

Secondly, once you have an account at bookglutton.com, you can maintain a collection of books that can be uploaded from many free sources, such as Feedbooks.com, or you can purchase books from a number of publishing houses, including O'Reilly Media, McGraw-Hill, and Random House. The only restriction on uploads is a valid epub format source.

Lastly, and most interestingly, you can share your reading with a private group or the public. This is done via two accompanying features: an annotation space labeled "MARK", for adding marginalia linked to specific paragraphs in the text, and a chat space to interact with other readers. Both features are unobtrusive, but accessible. It is easy to see how these features can be exploited for instructor notes, student annotations (public or private) and for student discussion.

BookGlutton offers an embed widget that allows the book to be accessed from any blog, wiki or other website that can accept the Javascript embed code. Below is an example using "Ebooks: Neither E, Nor Books" by Cory Doctorow.

Selecting the embedded book, opens the ebook reader in a lightbox presentation format. Bookglutton also makes available an introductory video explaining their service, which is shown below.
