With generous support from the CLIR Hidden Collections grant project, Avery Architectural & Fine Arts Library was able to catalog its long-held, but long-hidden, collection of American viewbooks. This multi-year project revealed the depth of Avery's extensive viewbook collection -- more than 4,000 items representing big cities and small towns, famous landmarks and ones long since forgotten - a unique historic catalog of our nation's changing landscape. This online exhibit showcases a selection of 50 viewbooks from Avery's collection.
