If you are looking for an excellent source of free eBooks, I strongly recommend Project Gutenberg. It is a source for thousands of books that are in the public domain, and the books are all free of charge! You won't find modern books on Project Gutenberg, but there are a host of classic works of literature. As an English teacher, I constantly point my students toward the website for examples of good reading. In an age of digital learning, Project Gutenberg is a must-use site. I have downloaded both eBook and audio book files there, and have never been dissatisfied. If you are looking to save money, then download the classics for free using the Project Gutenberg web service. NOTE: I have no connection to Project Gutenberg. My only reason for discussing it here is to provide access to free books for my fellow forum participants. Enjoy!
