*The SAA-ACRL/RBMS Joint Task Force on the Development of Standardized Holdings Counts and Measures for Archival Repositories and Special Collections Libraries is pleased to announce the release of its revised draft Guidelines for Standardized Holdings Counts and Measures for Archival Repositories and Special Collections Libraries <https://www2.archivists.org/groups/saa-acrlrbms-joint-task-force-on-holdings-metrics/guidelines-for-standardized-holdings-counts-and-measures-for-archival-r>. The Guidelines are the product of the Task Force’s efforts to analyze, incorporate, and address community feedback received in response to its draft release between January 11 and March 3, 2017, and as summarized in the Task Force’s July 20, 2017 Annual Report to the Standards Committee. <https://www2.archivists.org/sites/all/files/ReportStandardsSAA2017.pdf>The Guidelines are available both online and as a PDF via this SAA website:https://www2.archivists.org/groups/saa-acrlrbms-joint-task-force-on-holdings-metrics/guidelines-for-standardized-holdings-counts-and-measures-for-archival-r <https://www2.archivists.org/groups/saa-acrlrbms-joint-task-force-on-holdings-metrics/guidelines-for-standardized-holdings-counts-and-measures-for-archival-r>. The Guidelines reflect a multi-year effort to develop definitions and best practices for quantifying the holdings of archival repositories and special collections libraries. The Guidelines address both the wide range of types and formats of material typically held and the different ways collection material is managed and described. The Task Force invites comments on the revised draft.
