Many newspapers have not been digitized but have been preserved on microfilm. Although microfilm is not as convenient as digitized newspapers, they may be a researcher's only option to access a newspaper. Microfilm can be requested through Interlibrary Loan for use on the Libraries' microfilm readers. To identify newspapers available on microform try searching Worldcat. A particularly important collection of newspapers on microfilm can be search through the CRL newspaper catalog. You do not have to determine if a newspaper is available on microfilm to make a request. If you have the title and date of a newspaper issue or range of issues that you need you can make a request using the ILL form and the library will try to identify a copy on microfilm.
