Microforms @ Pitt

This is a guide for finding and using the microforms collection in the University Library System.

What are Microforms?

Microforms are made of either film or paper and contain reproductions of documents too small to be seen by the human eye. Images of the different types of microforms available in the ULS collections are below.

Why Do We Use Microforms?

In the mid-20th century, libraries and archives began using microforms as a way to preserve decaying newspaper collections. Deteriorating books and newspapers were preserved on film in order to maintain accessibility and use.

There are still many advantages to microforms today:

  • Microforms are compact and inexpensive, allowing libraries to expand collections, while reducing storage and other costs.
  • When produced properly, microforms have a life expectancy of up to 500 years and are easy to maintain.
  • Access to rare, valuable, or fragile items is enabled and there are very few incidents of microform theft.
