If the library catalog indicates the location is “Art & Architecture,” it’s more than likely a circulating book located in the “Open Stacks.” These books can be pulled from the shelves without assistance and checked out for use outside the library, provided they aren’t checked out already. There will always be a staff member available for help with finding materials.
If items you are seeking are currently in use by another patron, please request another copy through the library catalog or Interlibrary Loan. They can be placed on hold for you to pick up at whatever library location is most convenient to you.
