"Planning for Harvard's Future" is the title of an exhibition currently on display in the main lobby and second floor lobby of Widener Library.

The recently instituted Planning Office, headed by John W. Teele '27, has prepared the exhibition, which describes the historical physical development of the University and forms a background to the Program for Harvard College.

A section of the display visually represents the building requirements called for in the $82.5 million fund drive, although the illustrations are not specific plans regarding designs or sites.

Included in the exhibition are a new University Health Center, undergraduate Houses, freshman dormitories, housing for married students, a theatre, Behavioral Science building, Chemistry building, and new building for the Graduate Schools of Business Administration and Education.

The exhibition in Widener is one of several which have been planned for returning alumni. The writings of the Class of 1932, including books, articles, and reprints, are also on display at Widener.
