From the Vault’s welcome page:
The Publetariat Vault is a searchable database of independent literary works for which the authors own all rights free and clear and are interested in selling those rights, with accompanying sales data and reader reviews to take the guesswork out of determining commercial potential in the mass market—and it’s FREE for you to use.
Search by genre, topic, keyword, recommended reading level and more to find the kind of content you want to acquire
Indie (Self-Published) Authors:
The Publetariat Vault also provides a groundbreaking service to you: the opportunity to get your indie book in front of the publishers and producers who are seeking proven books for low-risk acquisitions. If you’ve ever thought that if publishers or producers only knew how well your book is selling, how great its reviews are, and what a great job you’re doing to promote both it and yourself, they’d snap up the rights in an instant, then the Vault was made for you.
– The first 300 listings to be published will be listed for free for 90 days, beginning on the day the Vault opens for pro searches
The Publetariat Vault is currently under construction, with a planned launch at the end of June, 2009. Note that member registrations for the Vault will not be processed until the site go-live date, which will be announced on Publetariat, on this site and elsewhere.
