The University Libraries have expanded hours at the Mellon Institute Library, and the Roger Sorrells Engineering & Science Library to better serve the CMU community.
 
The Mellon Library, located on the fourth floor of Mellon Institute is now open 24 hours, seven days a week. 24-hour library access is limited to CMU affiliates with photo identification. Mellon Library visitors not affiliated with CMU can access the library Monday through Friday, 8 a.m. – 5 p.m. To visit the library, sign in at the Mellon Institute security desk, located inside the Bellefield Street entrance.
 
The Sorrells Library, located on the fourth floor of Wean Hall, is now open 24 hours, five days a week. When the library opens at noon on Sunday, it will remain open until Friday night at 9 p.m. without interruption. Saturday and Sunday hours can be viewed online. 24-hour library access is limited to CMU affiliates. A valid CMU ID is required to enter Wean Hall and Sorrells Library after midnight.
 
These extended hours are part of the Libraries’ mission to ensure that the services and physical spaces of the Libraries enhance the quality of the student experience, allowing the community to interact with new technologies; to access collections; to engage with and learn from librarians; and to do their work, alone or in groups.
