To renew books, please use the following guide. Books from the Members' Collection have a loan period of three weeks, and may be renewed one time. You may request an additional renewal by contacting the Library via phone or email, but please keep in mind that our collections are here for all to use, and your prompt return of materials is appreciated by others who would also like to access these items.
If there is an error message when you attempt to renew,
1. Navigate to the Library's homepage. The URL is: https://www.nybg.org/learn/mertz-library/

However, if you do not have your barcode, please email the Library and the Librarian will send your barcode to you. You will also need your barcode to access our online databases, so do not hesitate to ask if you require this information.
