The Osher Map Library is willing to accommodate educators who wish to design their own lessons using items in OML’s collections to be conducted at the library. Select original materials may be displayed for mature students in a secure room. Due to the limited size of the secure space, we are only able to offer this to small groups with less than twenty students.
