This collection contains colored slides from various places that Francis Weeks traveled in Western Europe, Asia, Egypt and South America between 1960 and the early 1980s. There are a great number of slides of cathedrals and museums.

Additionally, there are several slide inventories from when some of these slides were contained in Francis Weeks’ own Winnisimet Collection of slides.

The collection consists of personal and professional papers of the architect Edward H. Bennett. The collection is arranged into two series. Series 1 includes correspondence, drafts, and plans from throughout Bennett's career. The most significant part of the collection is the correspondence between Daniel Burnham and Bennett, that reveals some of Burnham's thoughts regarding the 1909 Plan of Chicago. There are letters with other professional colleagues as well. The photographs span both  the professional and personal realms, including many photographs of three generations of the Bennett family and many photographs Bennett took or acquired to inform his architectural projects. There are several sketchbooks and scrapbooks and also several books of study photographs.
