The Library building is directly west of the entrance (visitor services) area. Library materials circulate to Los Angeles Arboretum Foundation members. Join today!

Library Location

The Arboretum Library is located within The Arboretum. Go straight through the double doors on the left (west) of the entrance rotunda.

History of the Library

Library Interior Sept. 4th, 1959.S-1071.1

 "One of the nine objectives put forth in 1948 by the California Arboretum Foundation Board administrator for the newly founded Los Angeles State County Arboretum, was library service. A reference library for staff members only was the original intent in planning for a library, but since Arboretum objectives included both research and public information, it was soon apparent that the library must eventually become both a staff and a public resource."

From: What’s in an Arboretum Library by Lydia S. Bowen
