Requesting Closed-Stack Materials
For delivery of materials from closed stack collections, requests typically must be made at least one hour, and sometimes two hours, before the reading rooms close. Details are available in the reading rooms and on their home pages.
Each reading room also has a reference collection that is openly available during reading room hours.
