Selected items from the Yerkes Observatory Library circulate only on location to current faculty staff, students and registered borrowers. A great deal of the collection at Yerkes is duplicated in The John Crerar Library. The Crerar copies may be consulted there, checked out, or recalled if checked out by another user. In cases where there is only a Yerkes copy available, please contact Crerar Circulation.

For further information, please contact the Crerar Circulation and Reserves Department for assistance.
