In addition to its permanent exhibition galleries, the Museum mounts a series of changing exhibitions over the course of the year. Information on current and future exhibitions may be accessed here. The Museum also maintains an archive with information on past exhibitions mounted or hosted since 1997. These exhibition archives are organized by year, and are available here. To better offer visitors meaningful opportunities to engage with art, and to place objects into one or more meaningful contexts, the Museum also is developing online exhibitions. In some cases these represent adaptations of previous physical exhibitions. In others, they represent shows designed from the outset to be web-based, and focus on more detailed treatment of materials that are difficult to adequately interpret in galleries alone (e.g., ancient coins), or to create shows reaching beyond the physical walls of the Museum.
