The archival processing of the collection began in fall 2004 by students from Pratt Institute, School of Library and Information Science and concluded in spring 2008. A total of 159 graduate students participated in this project expending upwards of 6,500 processing hours. They are:

The records were donated to Brooklyn Historical Society (BHS) in 2014. In June 2015, BHS archivist John Zarrillo, assisted by Stephanie Coy, prepared the collection for transfer from Packer Collegiate Institute to BHS. This process included the consolidation of the collection from 445 boxes to 388 boxes. The collection's arrangement and description remained largely unchanged, although adjustments were made in certain areas to aid researchers. The finding aid and container list was converted from a Word document to an EAD XML file and imported into Archivists' Toolkit in July 2015.

In September 2015, John Zarrillo commenced processing approximately 80 cubic feet of records that remained on-site at Packer. This work was completed with the assistance of Katie Bednark and Laurin Paradise. Subsequently the arrangement and description of the collection was completely revised by the BHS archivist in June 2016.

In January 2017, the Packer Collegiate Institute collection (ARC.130), which was comprised of accessions 1985.061 and 1987.016, was incorporated into the Packer Collegiate Institute records (2014.019) by John Zarrillo. These materials include assorted catalogs, publications, and other ephemera. The provenance of those files is as follows: Portions of accession 1985.061 were the gifts of Katharine B. Cronkhite, 1960; Mrs. Joseph Keppler, 1966; Katherine W. Sawford, date unknown; and the Packer Collegiate Institute, date unknown. Remaining materials from this accession were acquired sometime prior to 1985. Accession 1987.016 was the gift of Georgia Giddings, 1987.

The majority of audiovisual material in this collection was digitized during 2019-2020. Material that was not included in the scope of the digitization project included close duplicates, unidentified B-roll, and items that were determined to have degraded beyond the point of successful transfer.

Born-digital material in this collection was donated on two 3 1/2 inch floopy disks, thirteen CDs, and twenty-five DVDs. The disks were imaged using Bitcurator-2.0.14. No viruses or personally identifying information was identified during imaging. The finding aid was updated to reflect newly imaged material. In instances when other copies of the content had previously been digitized (largely from MiniDVs), these items were not updated. A small number of disks were not able to imaged successfully (IDs 2014_019_media_007, 2014_019_media_014c, 2014_019_media_017i, 2014_019_media_017j, 2014_019_media_021.
