The need for an OER textbook on conceptual physics led to the discovery of a short book Matthew Raspanti posted on the internet back in 2008. He agreed to a CC-BY-NC-SA licence that permits the text to reside on Wikiversity as a pdf file. It is available as a single 162 page document, as well as 20 much shorter documents to facilitate online navigation.

Each of these 20 sections links out of a WIKI page that will permit the submission and sharing of ancillary materials under a CC-BY-SA license. These wiki-pages can be organized to host an arbitrary number of submissions by students, as well as by instructors.
