  Accession Number
  
  
  
  This unique number is assigned to an individual artwork as part of the cataloguing process at the time of entry into the permanent collection.
  Most frequently, accession numbers begin with the year in which the artwork entered the museum’s holdings.
  For example, 2008.3 refers to the year of acquisition and notes that it was the 3rd of that year. The DIA has a few additional systems—no longer assigned—that identify specific donors or museum patronage groups.
