Listed record inventories

Selected holdings and indexes for Carbon County, checked against the repository descriptions linked below. Date spans may contain gaps; an index is not a complete set of original records.

Newspapers

See the repository's descriptions and search options

Repository access note: Selected newspaper titles cataloged by the Library of Congress with explicit county geography. Priority is given to titles beginning by 1950; up to five later titles are included where no earlier dated title is listed for that county. Dates describe publication history, not the issues available at a library. Multiple format records with the same title, place and dates are grouped. The catalog may describe paper, microfilm or online resources. Open ends and the word Current reflect the catalog description; confirm present availability and exact holdings with the libraries listed on the linked record.

Sources: the catalogs and repository descriptions linked on the entries above. Selected inventories do not establish complete coverage of every record type or online access to original documents. Read the repository access note for source dates and limitations.
