OAPEN is a site offering a lot of books of every description free for the downloading. Search what you’re looking for and you may be happily surprised to find it.
The OAPEN Library contains freely accessible academic books, mainly in the area of humanities and social sciences. OAPEN works with publishers to build a quality controlled collection of open access books, and provides services for publishers, libraries and research funders in the areas of deposit, quality assurance, dissemination, and digital preservation.
On this #WorldBookDay it’s sure to be a useful thing. With special thanks to my best Newman U. friend, Richard Goode for pointing it out. I’m adding it to the useful sites section of the nav panel.
