The National Gallery of Art in Washington DC has grouped the services of its Education Division conveniently at this section of its site. For example, for classes planning in-person trips, the site lists various thematic tours designed to teach geography, history, or language arts using fine arts; each listing includes instructions for ordering accompanying teaching materials and reservation forms for booking tours. Teachers will also find information about the Gallery's loan program which allows them to borrow teaching materials, schedules of workshops at the National Gallery and at other museums around the country, and news about the National Gallery of Art's Teacher Institute, held every summer. In addition, there are links to online educational programs, many created to accompany past exhibitions at the Gallery, such as in-depth studies of Thomas Moran or Mark Rothko, exhibited in 1997 and 1998.
