Modern art lovers rejoice! The Guggenheim Museum in New York has just made more than 200 books about modern art available online. Not only can you read them online, but you can download them in PDF or ePub formats—for free—at the Internet Archive.

For over half a decade the museum has been digitizing its exhibition catalogs and art books, placing the results online. So whether you want to study up on some art history with titles like Picasso and the War Years and Expressionism, a German intuition or read the first English translation of Kandinsky's On the spiritual in art, you've come to the right place.

The collection also includes catalogs of retrospective exhibitions on masters like Paul Klee, Robert Rauschenberg, Max Ernst, Francis Bacon, and Mark Rothko. Or you can dig deeper into Chinese art in the 20th century and the craftsmen of ancient Peru.

If you're planning a visit to the Guggenheim, you may also want to consider boning up on the collection, from sculpture and works on paper to Masterpieces from the Guggenheim Collection: From Picasso to Pollock. Whatever you are after, dig in and get ready for a crash course in modern art.

The Guggenheim Museum's full collection of digitized catalogs and art books is available at the Internet Archive. And they aren't the only New York institution releasing digitized information about their collections. Recently, the MoMA released images that allow you to explore every exhibition the museum's held since 1929.
