Founded in 1945, the Museum of Contemporary Art in Chicago features contemporary photography, video, film, sculpture, and other visual arts, both in its galleries and its extensive onsite performance series. For persons considering visiting the museum, the site contains information on current and upcoming exhibitions, which have featured artists from the sculptor Alexander Calder to Gillian Wearing, the British artist perhaps best known for her video installations. The Web site also contains "Website Insights," which is the online searchable archive of the MCA's holdings of approximately 6,000 objects. The search engine for the collection is quite flexible, allowing visitors to search by artist name, nationality, title of work, medium, and the decade in which the work was produced. For educators, the site also contains lesson plans to use with different age levels and with different pieces of art from their collection.
