Gluejar is a brand new project (it hasn’t even started yet) with a noble idea–the creators want to “unglue” popular books and make it publicly available for free to readers.
From the site:
Authors and publishers choose a funding goal. Book lovers chip in to meet it.
Anyone will be able to kick off a pledge drive for a favorite book on our upcoming web site unglue.it. Gluejar will work with rightsholders to determine a good price, and anyone can contribute toward meeting it. When the goal is met, rightsholders will be paid in exchange for making their works available under a Creative Commons license. The book becomes free for everyone to read and share.
