Using Titles in the Public Domain Core Collection

All titles in this collection are freely available for use.  If you wish to use them without making any customizations, you can access them directly from the Public Domain Core Collection Catalogue page.

Customizing Core Collection Titles

Any of these titles can be customized to reflect the requirements of a particular course.  How you make a customized version will depend on your location and the software you have available.  The easiest way to customize a book is to clone it to another Pressbooks site and edit it there, but other editing options are available.


All titles are available from the Public Domain Core Collection site and are licensed so that you can copy and edit them.  To create a customized version, log into your eCampusOntario or institutional  Pressbooks account, and clone a copy of the book.
