The Reeves-Reed Arboretum library offers a collection of books, catalogs and videotapes about gardening, nature and the environment. The library is open to the public, and materials may be borrowed by Arboretum members. The library is located inside Wisner House, and is open Tuesday to Friday, 9:00 am-5:00 pm.
The Arboretum has many period photographs, letters and drawings. The New Jersey Historical Commission and the Union County History Grant program have made possible the creation of an organized, indexed archive that is properly stored and available for controlled use by staff, scholars and the general public.
