From the Unglue.it "About" page:

At Unglue.it, you can pledge toward creating ebooks that will be legally free, worldwide. These books have already been traditionally published, but they're stuck: legal restrictions keep you from being able to enjoy and share them.

Unglue.it gets them unstuck. Authors and publishers decide what amount lets them freely share their books with the world while still making a living. We raise that fee here through crowdfunding: people like you chipping in. When campaigns succeed, the rights holders get paid, and they issue a free electronic edition under a Creative Commons license.
