The Heritage Center holds microfilms of all major newspapers published in the city of Fresno, and from some other localities in Fresno County and elsewhere in California. There is an alphabetical list by title and an alphabetical list by place of publication.

Most important among the Room's holdings are the Fresno Weekly/Daily Evening Expositor (1870-1898), Fresno Weekly/Evening Republican (1876-1932), Fresno Weekly/Evening Democrat (1902-1907), Fresno Herald and Democrat (1907-1913), and Fresno Herald (1916-1924).

A complete microfilm file of the Fresno Bee (1922- present) is available for use in the Readers' Service area on the library's ground floor. The Bee file from 1986 to the present is searchable electronically at Library Internet terminals. Note: This resource is most useful for feature article content; some items, such as obituary rosters and paid funeral notices, might not be available from this database.

  • Clovis Independent (1916-present), at Clovis.
  • Fowler Courier (1894), at Fowler.
