The Quarterly abstracts of Baltimore passenger lists were first compiled in 1820. Beginning in 1820, U.S. Customs collectors were required to send quarterly copies of the customs lists to the U.S. Secretary of State who published transcripts for Congress. These quarterly abstracts or copies give the quarter-year of an individual's arrival and sometimes the port of embarkation. Passengers' given names were usually shortened to the initial letter, but otherwise the information is the same as that found in the original lists. The abstracts should only be used when the original list is missing. The abstracts also have many gaps and some years are missing. The Library has the abstracts for the following years: January 1820 to December 1845 July 1848 to September 1850 March 1857 to June 1869.
The federal records are supplemented by the "city lists" which were submitted to the mayor of Baltimore according to state law between 1833-1866.
"The manifests were filmed as they appeared in bound volumes. Date spans may overlap."
