Giggles, Thank you for this.
De nada Sam. Perhaps over-doing it, but a few other helpful resource spots with free ebooks:http://www.puritanlibrary.com/http://www.chapellibrary.org/literature/http://www.reformationfiles.com/
On sermonindex.net we are building a set of epub files that are "eSermons" which will be shorter sermons and resources to encourage saints in their daily walks with Jesus Christ. We will be pulling out some of the best sermons from all different christians from different theological points of view but the emphasis will be the Person of Jesus Christ and His life in the believer.http://www.sermonindex.net/ebooks.php
