Because newsprint deteriorated quickly, newspapers could not be stored archivally for the long term. Microfilming print material became a way to preserve newsprint for future use. Microfilming also became a way to capture a large amount of print material in a much smaller and more compact format. Some microfilming of material was done in house at Crerar Library. Other material was acquired. In addition to microfilm, microcards and microfiche were used to capture scientific and technical information including content from scientific journals and information about standards for working with materials such as steel.
The Library still holds significant microform and microfilm collections in Regenstein, which can be viewed there with a microform reader.
