The Williams Visual Resources Center has a collection of over 22,000 historic lantern slides some of which continue to be used for teaching by Williams art faculty. Lantern slide projectors are available for use in all art history classrooms. Select lantern slides, in particular architectural plans, have been scanned and added to the Williams VRC Collection. The hand-colored lantern slides are being scanned and added, and the glass stereo lantern slides dating from 1882 are being added as both stereo and single views.
