I found a catalog listing that mentions Mezzanine. What does that mean?
This is a special collection apart from the main stacks. Just bring the book's call number to the Reference Librarian who'll page it for you. Some Mezzanine books may be checked out. Others are for room use only and will require leaving your ID at the Circulation Desk.
I found a catalog listing that mentions Closed Stack. What does that mean?
These are rare, especially valuable or historically significant items housed behind the Circulation Desk. Bring the call number to the desk and the book will be paged for you. The desk will hold your ID and you'll be able to consult the book in the library.
Where is Oversize?
At the end of the books with N call numbers in the third room on the right as you enter the library. Oversize books are for library use only and may not be checked out.
What is the FLAT classification?
These are bulky volumes that lay flat on shelves at the end of the books with N call numbers in the third room on the right as you enter the library. FLAT books are for library use only and may not be checked out.
I'm interested in looking at a Cooper Union thesis from a prior year. How do I do this?
After checking the online catalog, bring the call number to the Reference Librarian, and that person will page the thesis for you. The Circulation Desk will hold your ID while you consult the thesis in the library. Cooper Union theses prior to 2004 do not appear in the online catalog. You will need to search the Archives card catalog (next to the Reference Desk) for Cooper Union Master's and PhD theses prior to 2004.
