Using games in the library classroom is an active learning strategy that can increase student engagement. However, not all librarians are equally familiar and comfortable with bringing game-based learning to the library. Game On for Information Literacy is a brainstorming card game to help librarians create games for information literacy and library instruction. Inspired by other successful brainstorming card games, this game was developed, playtested, and iterated over several years in workshops, graduate-level MLIS courses, and professional development programs. Game materials are all available to download, use, remix, and share.
