The Association of Game & Puzzle Collectors is a group focused on the collection and preservation of old games and puzzles. The organization holds an annual gathering for trading games and puzzles, as well as sharing information on their history and development. The AGPC maintains an archive of the rules for a number of out-of-print games, a catalog of U.S. games published through 1950, and formerly kept a collection of game industry materials (such as magazines and company catalogs). The latter collection was donated to the Strong Museum in 2007.
