Carl Stitz and I have been granted sabbaticals from our respective institutions for Fall 2016 to edit and enhance the Stitz-Zeager Precalculus book. It is our intention to have the 4th edition ready by January 2017.
The .pdf version of the book along with all of the LaTeX code will be posted on our website www.stitz-zeager.com when we're done with the revisions.Of course, this is good news for their project, but it also shows that their respective institutions, Lorain County Community College and Lakeland Community College, are willing to commit resources to support and advance an open-source textbook. Both institutions should be applauded for their support. If you find yourself in a similar position--trying to justify a sabbatical to work on an open-source project--perhaps point at these two colleges as precedent.
We look forward to the next edition of the text.
