Looking for an idea for an upcoming exhibit? Need some alternatives for an interactive activity? Want to know if anyone else has installed an outdoor exhibit at a bus station? You’ll want to explore “Exhibit Files,” a free online collection of exhibition records and reviews for exhibit designers and interpretive planners.  The Association of Science-Technology Centers launched this website in 2007 with funding from the National Science Foundation, but despite those affiliations, you’ll find plenty of files related to history, including a case study of Lewis & Clark (the national Bicentennial exhibition); a review of Terror House in Budapest by Daniel Spock of the Minnesota Historical Society; and a case study of a low-tech document-based interactive exhibit at the Missouri State Archives. Because most exhibit techniques can be used with any subject, you can adapt many ideas for your specific needs. The files can be searched by title, date, tag, or topic (such as history or architecture).   And if you have an exhibit experience to share or you’re looking to solve a problem, you can join for free and become one of the nearly 3,000 members.
