A Note About Third Party Sites

The primary function of this site is to help students find educational materials on other sites. Textbooks, particularly those that have been self-published, are bound to include the opinions of their authors. Those opinions may or may not coincide with mine.

I do my best to evaluate each item included in the list for quality. I have no way of knowing, particularly with the more advanced materials, if the information is correct, based on unproven theories or timely. Students should evaluate each resource the same way they would if they were standing in their university library choosing materials for a research project.
