The accession record books list accessions of the United States National Museum in order of receipt for the years 1859-1921. For the years 1859, 1860, and 1861, accession numbers begin anew each year. Beginning in 1862 numbers are sequential without regard to year.
Accession record books are a brief record of the main accession file, and with that file, are indexed by an alphabetical card index. In some cases, accession entries are duplicated in volumes.
