One of the things I did when working on The Letters of Sylvia Plath was to acquire copies of the Varsity Handbook for 1955-1956 and 1956-1957. Plath herself had these and used them like a bible for learning the ins and outs of life at Cambridge. I was particularly interested in the maps as they give the flavor and feel of the town, the colleges, and the university at that time period. They were indispensable for contextualizing some of Plath's experiences as I read them in her letters and worked on writing footnotes. Here is the cover for the 1955-1956 Varsity Handbook . If I remember correctly, this Handbook lacked the maps. So that was why I bought the 1956-1957 one... because I did have the maps.
