The Society sells a wide selection of used, rare, and out-of-print books.

Some items are available online, below.

The widest selection is sold through our quarterly book auctions. The catalog is available for browsing online and online bids are accepted until 4pm the Thursday before each Friday sale.

Over four days each August, crowds of bargain-shoppers descend on Lancaster Mennonite Historical Society for the Bookworm Frolic, an outdoor sale of over 40,000 used books.
