We’ll adhere to another tradition this year: offering O’Reilly Press books at large discounts during the OpenFest. This time around, our friends at ITBookshelf will provide the books. The full list is available at http://openfest.itbookshelf.com/, yet not all books will be in stock at OpenFest. To secure a copy, we recommend you use the site. In case you need an invoice, don’t hesitate to contact them at firstname.lastname@example.org.
