Research Monographs and Textbooks (7)

For many students around the world, educational resources are hardly affordable. Therefore, I have decided that my recent books should remain independent, non-profit, open-access projects. Whilst, for some people, the presence of a “designer tag” from a major publisher might still be a proxy for quality, it is my hope that some of the following items will prove useful to those who seek knowledge for knowledge’s sake. Please spread the word about these projects. Thank you.
