Interlibrary Loan Services

The interlibrary loan office borrows and lends material through the interlibrary loan subsystem of OCLC. The LuEsther T. Mertz Library of The New York Botanical Garden can supply physical items from its collections on interlibrary loan to qualified libraries within the United States and Canada only. Electronic copies that do not exceed copyright restrictions can be supplied to any library worldwide. The Library does not lend periodicals, oversized books, fragile material or material published prior to 1945. For further information, please email the Library.  

Please check the Library’s online catalog before placing a loan request.   

Loans are sent out for a one month period and are not renewable. The Library charges $20.00 per loan request and additional fees may apply to cover the cost of shipping excessive weight or multiple volumes. 

The LuEsther T. Mertz Library is a member of the New York Metropolitan Library Council METRO, Biodiversity Heritage Library BHL, and the Bio Information Science Consortium  BISC, offering complimentary loans to members with whom we have reciprocal agreements.  Additionally, the Library also has reciprocal agreements with other institutions that are members of The Council on Botanical and Horticultural Libraries (CBHL).

The copyright law of the United States (Title 17, United States Code) governs the making of photocopies or other reproductions of copyrighted materials. Under certain conditions specified in the law, libraries and archives are authorized to furnish a photocopy or other reproduction. One of these specified conditions is that the photocopy or reproduction is not to be “used for any purpose other than private study, scholarship, or research”. If a user makes a request for, or later uses, a photocopy or reproduction for purposes in excess of “fair use”, that user may be liable for copyright infringement.
