Resource List

In many parts of the world, academic books are not adequately available, and almost everywhere they are very expensive.  Fortunately, the Internet contains many open-access texts created by university professors, nonprofit groups, or governments, with useful information in the sciences, the humanities, and medicine. These books can be downloaded for free by anyone and most of them can be printed out for free. I have compiled a list of some of these sources, as well as links to other resources like the Open Textbook Library and FreeTechBooks. I have also included some links to related educational resources such as educational videos and online courses, as long as they are free of charge.
My name is John J. Dziak and my day job is as an associate research professor in statistics at the Methodology Center at the College of Health and Human Development of the Pennsylvania State University. I am maintaining this site as a volunteer — as a caveat, I don’t have any expertise in most of these subjects.

I can’t evaluate the resources in the article, but they may be useful. I have tried to include only resources with useful information from respectable sources. However, this is only a directory and I cannot endorse or take responsibility for all the contents of all the sources. Occasionally I might not agree with all of the opinions or recommendations in a book, and most often I simply don’t have the expertise to determine whether a book is accurate. As always, it’s important to use multiple sources and your own common sense. Documents marked as (CC) are under some kind of Creative Commons license, which usually means they can be freely distributed under reasonable conditions (like not changing them or taking personal credit for them). Some other documents, such as those from Hesperian Health Guides, do not have this license, so you can use them personally but should ask for permission before redistributing them, in order to respect copyright. If you have suggestions or concerns please email me at dziakj1@gmail.com  or jjd264@psu.edu. This site is dedicated in memory of Dr. Robert Franz.
