This document summarizes the creation of eBooks from open educational resources (OER) created as part of the PARiS Project at the University of Nottingham. Five OER modules on sustainability were converted to eBooks in various formats, including iBooks, ePubs, and mobi files for Kindle. These eBooks were made available through multiple platforms like the Apple iBook Store, Smashwords, and on the university's OER site.
