The Museum at the Sterling and Francine Clark Art Institute may currently be closed for renovation (until July 4, 2014), but in the meantime digital collections from the Library at the Clark are still available online. The Library's special collections are diverse and include formats such as artists' books, photographs, clippings, digitized books, archival finding aids, and ephemera. One important collection is the David A. Hanson Collection of the History of Photomechanical Reproduction. This collection documents the history of the methods used since the early 1800s through the 20th century to reproduce and print artwork in books as well as for the image-buying public. Suggested browse terms, with the number of items of each type indicated in parentheses, are Collotypes (85), Halftones (62), Photolithographs (44) and Woodburytypes (31). Other digitized collections document the history of the Sterling and Francine Clark Art Institute, and nearby Williams College, such as the "Newsletter of the Williams College Graduate Program in the History of Art.”
