Circulation desks

The Main (Gardner) Stacks are served by both the Doe Circulation Desk and the Moffitt Circulation Desk (closed through August 2022).

At both circulation desks, library users can check out books from Main Stacks and NRLF, place searches for items not found on the shelf, and pick up paged or recalled items. Library materials from any campus library may be returned to either desk. Both desks close 15 minutes before the library closes. The Borrow page contains detailed information about check-out limits, loan periods, paging materials, and more.

The Doe Circulation Desk is located on Level A of the Main (Gardner) Stacks. In addition to the services noted above, library users can collect keys for the study rooms in Main Stacks until 9 p.m. Sunday through Friday and 5 p.m. on Saturday.

Browse

There are designated reshelving areas throughout the Main (Gardner) Stacks on Levels B, C, and D noted with signs. The library requests that users not reshelve material, but place items not needed in the designated areas for staff to pick up. This helps us keep track of which items have been used as well as ensures they are reshelved correctly.

There are 400 seats available for individual study throughout floors BC and D. All areas of the Main (Gardner) Stacks are intended for quiet study.

Extreme silent study areas and study carrels are also provided. Group study rooms may be reserved by UC Berkeley students. Main (Gardner) Stacks is open to:
