Going to college can be an expensive ordeal. Affording tuition is challenging enough, but other costs such as textbook purchases are usually on top of tuition, room, and board.
Open Textbook Library has textbooks on extensive college subjects with free licenses with Creative Commons, making it free for anyone to use and change.
All books are free and easy to download. Their collection is not academically-oriented but predominantly classics, including memoirs, fiction, and short stories.
