Slocum Puzzle Collection

The Jerry Slocum Collection of mechanical puzzles embodies a lifetime pursuit of the intriguing and the perplexing. The result is the largest assemblage of its kind in the world, with over 30,000 puzzles and 4,000 puzzle related books. Unlike word or jigsaw puzzles, mechanical puzzles are hand-held objects that must be manipulated to achieve a specific goal. Popular examples include the Rubik's cube and tangrams. The puzzles in the collection represent centuries of mathematical, social, and recreational history from across five continents.

About 400 puzzles from the larger collection are on display at the Lilly Library in the newly refurbished Slocum Puzzle Room. The bulk of the collection will be transferred to the Library in installments over the coming years.

Exploring the collection

An online database of the collection is under development at the Indiana University Digital Library Program. Users may view images of selected puzzles by keyword-searching the database, or browsing the puzzle classification scheme developed by Mr. Slocum.

A 16-page illustrated catalog published to accompany the exhibition, A World of Puzzles: Highlights from the Jerry Slocum Collection of Mechanical Puzzles, Brainteasers & Ingenious Objects is available for purchase, price $4.00. Contact the Lilly Library by e-mail: or by telephone: 812-855-2452 for ordering information.
