In July of this year, HSP undertook a project to survey its microform holdings.  Microform includes both microfilm and microfiche.  Microfilm is like 35mm film, while microfiche is tiny images on a sheet of paper.  HSP holds approximately 23,000 microfilm reels and 10,000 microfiche leaves, including facsimiles of serials, vital records, manuscript collections, and other materials.
