The Public Domain Review: http://publicdomainreview.org/
"The Public Domain Review is a not-for-profit project dedicated to showcasing the most interesting and unusual out-of-copyright works available online.
All works eventually fall out of copyright – from classic works of art, music and literature, to abandoned drafts, tentative plans, and overlooked fragments. In doing so they enter the public domain, a vast commons of material that everyone is free to enjoy, share and build upon without restriction.
We believe the public domain is an invaluable and indispensable good, which – like our natural environment and our physical heritage – deserves to be explicitly recognised, protected and appreciated.
The Public Domain Review aims to help its readers to explore this rich terrain – like a small exhibition gallery at the entrance of an immense network of archives and storage rooms that lie beyond."
Some of my favorite articles are:
