Tisch Library, originally Wessell Library, is the principal library for the Medford/Somerville campus of Tufts University. The library holds 2.7 million volumes and serves as the main branch of the Tufts library system. The building was originally designed in a brutalist style by Shepley Bulfinch Richardson and Abbott. Construction started in January 1964 and the library was originally named after Tufts' eight president Nils Yngve Wessell. At a cost of $2.9 million the library was dedicated on September 1965. Wessell Library succeeded Eaton Memorial Library as the main library on campus and was constructed next to it. After a $21 million renovation, the library was enlarged in January 1996 and was renamed after Jonathan and Steve Tisch who donated $10 million for the project.
