The Metropolitan Museum of Art of New York is creating an ever expanding library of art books that users can freely read online and, in many cases, download as high quality PDFs for reading offline.

The books are lavishly illustrated, written by top experts in the field, and cover all eras, styles and geographic regions. There are books on African art, medieval architecture, modern and contemporary art, and prehistoric cave paintings.

Despite the large amount of volumes, you can narrow your search by title, author and keyword, choose the type of publication, theme, or collection department you want to browse, and even pick the format (PDF, read online only, print on demand, etc.).

At the moment of writing, there are nearly 400 titles available, but new titles are added every day.

Thanks to Roberto Ortiz for the lead.
