Public Domain Review
publicdomainreview.org
An online journal dedicated to the exploration of curious and captivating works from the history of art, literature, and ideas that have entered the public domain.
Why it is useful
Goes far beyond simply listing public domain content — each piece comes with substantial editorial context that makes obscure historical artifacts genuinely understandable. It is one of the best sources on the internet for discovering forgotten scientific illustrations, strange Victorian photography, and early experimental art that most people have never encountered. The quality of curation is exceptional.
