The Biological Laboratories Library is no longer a separate entity. Its collection is being merged into that of the Ernst Mayr Library (MCZ), with some items going to Cabot or the Chemistry Library. However, many books remain in the Biolabs Library in Room 1096 at 16 Divinity Avenue, and MCZ Library staff members are happy to retrieve them upon request. Contact the Ernst Mayr Library at 617-495-2475 or Dorothy Barr, 617-495-1348 or

The Ernst Mayr Library is currently open 9 am- 8 pm Monday through Thursday; Friday 9 am-5 pm; and Saturday (except holiday weekends) 10 am-1 pm. We will only be open from 9-5 Monday-Friday during Intercession, January 13-26.
