Over the last few years, the Guggenheim Museum has slowly released an impressive library of modern and historic art books in collaboration with the Internet Archive. The rare and out-of-print titles include books about Pablo Picasso, Roy Lichtenstein, Paul Klee, Jenny Holzer, Joseph Cornell, as well as several exhibition catalogs and books about the museum itself. You’ll also find publications on wide ranging topics from the Russian and Soviet avant-garde movement to collections of Chinese and Aztec art.
Many of the books first books appeared online in 2012 and the collection has grown to include over 200 titles that can be viewed online or downloaded in PDF or ePub formats. You can see the full collection here. (via The Creators Project, My Modern Met)
