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 are shown below. 

Microfilm: (35mm and 16mm reels of film) - positive copy (black background/white print) microfilm



Duplicate negative copy (clear background/black print and emulsion/shinny part on the back)

Microfiche (small sheets of film)
