Research and Instruction

As a relatively small collection within the Harvard Library system, the Arnold Arboretum Horticultural Library and Archives’ success is the result of the quality, dedication, and special expertise of each staff member. Teamwork, cooperation, courtesy, and respect coupled with the wish to share information with those who seek it are the guiding principles of the Library and its staff.

Our library staff is pleased to assist you with reference consultations, introductions to library and archival materials, and interlibrary loan requests (for onsite use only).
