American philosopher, Eugene Gendlin, has been noted for his influence in the fields of both philosophy and psychology. After earning a PhD in philosophy from the University of Chicago in 1956, Gendlin went on to serve as a professor of both philosophy and psychology at the university. Gendlin also collaborated with pioneering psychologist Carl Rogers. The Gendlin Online Library offers an extensive collection of Gendlin's published and unpublished works. This library contains 137 documents in total, and can be browsed by central themes or topics, such as Focusing, a therapeutic approach that Gendlin developed along with Rogers. While some of the items in the Gendlin Library must be purchased, many are freely available to the public. This collection may be of interest to students of philosophy and psychology alike, as well as to those who study the history of those disciplines.
