backlog

n. archival resources received by a repository but that have not yet undergone one or more archival processes

Notes

A backlog connotes materials that have been in a pending status for some time rather than temporarily. While the term backlog often implies a processing backlog, there are in fact many types of backlogs. For example, backlog can take a qualifier that refers to the nature of work to be done, such as an “accessioning backlog,” “cataloging backlog,” “preservation backlog,” or “processing backlog.”
