Microforms consist of microfilm, microfiche and microcartridge formats that contain images of printed and graphic material on a reduced scale. Back issues of periodicals are stored on microforms. Particularly notable is the microfilm collection of the Honolulu Advertiser and the Honolulu Star Bulletin dating back to 1929.

• Microfilm - film rolls on spools.
• Microfiche - small sheets of film.
• Microcartridge - microfilm in a plastic housing (Specifically, the Magazine Collection that is indexed in InfoTrac.)

Readers/printers for the microforms are available to view and print articles. Copies are 10 cents a page.
