 A Global Resource for Information About Plants


The Arnold Arboretum serves humanity as a premier destination for deepening understanding and appreciation of the plant kingdom. The Horticultural Library contributes significantly to this mission, stewarding a research collection of some 25,000 volumes on botany, horticulture, urban forestry, and more. The Library also houses the Arnold Arboretum Archives, which preserves and shares the Arboretum's history, its critical role in plant exploration around the world, and some 40,000 photographs. One of Harvard's only libraries to be open to the public, you may visit Monday through Friday, though many resources including title listings, archival and contemporary photographs, and the complete run of our journal Arnoldia are freely accessible online. more »
