Effective immediately, the McLafferty Annex will be closed to the public as part of the university’s project to move books from the storage facility to Morris Library.

David Carlson, dean of library affairs, said in an email to faculty Wednesday that the shelving construction and deconstruction, transportation and transfer of nearly 1.5 million books has made McLafferty a hazardous area.

“We are concerned about the safety of the public in what has become a construction site,” Carlson said in the email. “We also want to ensure a space that permits workers to work quickly and efficiently.”

Deliveries can still be made for online requests of volumes to the library. Books and print journals will be delivered twice daily Sunday through Friday to the circulation desk at Morris.
