PressBooks, a company that offers an online toolset for self-publishing, has partnered with BookBaby to help authors distribute their titles in eBook stores.

Thanks to the partnership, authors can create their eBooks online, manage all of the design and production of the title and then upload the title to 11 eBook stores including: the Kindle Store, Apple iBooks, Nook, and Kobo, all from the same interface.

Here is more from the PressBooks blog: “You can get to BookBaby easily from the PressBooks interface, just click on the new ‘Sell’ menu item in the left menu. Which will lead you to this page, from whence you may continue on to BookBaby and sign up there.”

PressBooks, the DIY self-publishing tool built on WordPress, is going open source. The digital publisher has plans to release a WordPress plugin under the open source GPL license around the end of January that will let the authors and publishers who use the tool create their own fully-customizable version of PressBooks.

The platform will still be free, but users can opt to pay PressBooks for hosting and maintaining their content for a fee.
