Abstractors search the ASL for the appropriate code for the document's supplying organization.
If an agency is listed, the abstractor places the ASL code in the corresponding cataloging field. If the agency is not listed, the abstractor fills out a form for a new ASL code to be assigned. This process ensures the accuracy and consistency of all information on document suppliers.
