This series contains prints, negatives, slides and transparencies of Segal's fine photography spanning thirty years, with the bulk of the series dating to a period of focused activity from 1984 to 1999. The series can be considered the result of two distinct periods in Segal's creative life: a long-time interest in fine photography without a disciplined or specific approach, from 1966 to 1983; and an active and informed pursuit of the subject, from 1984 to 2000.

This series contains exhibition catalogs and posters related to over forty years of exhibitions in a number of countries and in a variety of languages, including Japanese and Korean. Despite a prolific history of exhibition – Segal and his work were featured in over one hundred one-man exhibitions and over three hundred group exhibitions in the course of his life and beyond – there are relatively few catalogs and posters present in the collection.
