The Foundation continues to produce electronic versions of the books we publish. The latest addition to our e-book library is Principles of Psychology by Keller and Shoenfeld, or K&S as it is known to many. The title is now available in our Bookstore; and also through all major online retailers (click on the link to go directly to the product page): Amazon, Barnes and Noble, Google Play, iTunes, and Kobo. If you are planning to buy (or purchased already) a print edition of K$S through Amazon, the Kindle Edition is only $2.99
