For the first half of the Belfast project, Schwartz printed a large sampling of images on a less expensive, resin-coated paper, which he filed by year. The remainder of his prints were those he deemed "good" images and printed on fiber paper for exhibition or sale. They span the entire time period of the project, sometimes duplicating the chronological prints.

Collection is open for research, except Series V. Negatives, which are closed due to their format. Contact prints of most negatives are available in Series I. Contact prints.
