About Microfilm Collections

Special Collections has over 2,000 reels of labor-related microfilm.

Q: What is microfilm?

A: Microfilm is a roll of film containing very small pictures of scanned documents. Researchers use special machines to magnify the film.

How to Use Microfilm Collections

Reading microfilm requires special microfilm readers.

The Maryland Room has both older analog and newer digital microfilm readers. Patrons can scan and save images on the digital readers to a flash drive.

Staff in the Maryland Room are happy to help patrons learn how to use our microfilm readers.
