Louisiana Digital Library This database is available to anyone with a Louisiana public library card. The Louisiana Digital Library (LDL) is an online library of Louisiana institutions that provides over 144,000 digital materials. Its purpose is to make unique historical treasures from the Louisiana institution's archives, libraries, museums, and other repositories in the state electronically accessible to Louisiana residents and to students, researchers, and the general public in other states and countries. The Louisiana Digital Library contains photographs, maps, manuscript materials, books, oral histories, and more that document history and culture.
Your local parish library may provide access to genealogical databases. Depending on the subscription terms between the parish library system and the database owner, you may be able to access the database from home. Or, you may have to physically enter the local library to access the database. For example, the New Orleans Public Library provides access at home to databases like "Historic New Orleans Newspapers," "HeritageQuest Online," and "Sanborn Maps" for card holders. To access the "Ancestry Library Edition" database, however, you must visit an actual New Orleans Public Library in person.
Louisiana State Archives The Erbon and Marie Wise Genealogical Library is the public's primary link to the holdings of the Louisiana State Archives. Access to the thirty thousand cubic feet of records stored in the State Archives, as well as books on general histories, census indexes, immigration schedules, church records, and family history.
Library of Congress Although most of their resources must be used at the library, many guides and sources may be accessed online.
