Open Humanities Press
Open Humanities Press (OHP) is an open access publisher of contemporary critical and cultural theory. A grassroots initiative by academics, librarians, journal editors and technology specialists, OHP was formed in response to the growing inequality of readers' access to critical materials necessary for research in the humanities. OHP is dedicated to the highest intellectual standards and free, unrestricted access in equal measure. Launching in 2008 as a consortium of leading open access journals in continental philosophy, cultural studies, new media, film and literary criticism, OHP is committed to making scholarly works of outstanding quality and challenge freely available to a worldwide audience.
Project Gutenberg
You will find classic books from the start of this century and previous centuries, from authors including Shakespeare, Poe, Dante, as well as well-loved favorites like the Sherlock Holmes stories by Sir Arthur Conan Doyle, the Tarzan and Mars books of Edgar Rice Burroughs, Jane Austen, and over 15,500 other books. Books are almost always available in plain text format, with many in HTML and other formats. Other than books, additional content types include musical scores, movies and sound files. Most Project Gutenberg eBooks are in the public domain in the US, so tend to be from items published prior to 1923.

The advent of the Internet and the World Wide Web are making collaboration among educators on a global scale possible for the first time. We want to harness this exciting technology to promote learning and sharing.
