Reed College Library has a wonderful online exhibition and essay about artists’ books. Pulling items from their Special Collections, the exhibition includes works by artists such as William Kentridge, Gerlovin and Gerlovina, and Xu Bing. The collection contains excellent examples of modern book arts and provides page by page viewing of most items.
You can browse the collection by four main sections: livre d’artist (deluxe edition prints), avant garde, conceptualist, or contemporary. Or, chose to explore by artist. When Reed does not have an artist’s work online, they link to external websites about the artist.
The University Libraries also has a book arts collection with over 400 items available for students and faculty to view.
