|Palmitic acid residue on acetate coated aluminum disc.|
Data on this disc was successfully transferred after a cleaning.
|This disc is delaminated, but we were able to transfer data from the backside.|
|Data was transferable from this disc despite a little uneven surface.|
In 2010, an award from the Collections Care and Preservation Fund allowed Anacostia Community Museum Archives to conserve and reformat approximately 80 of 110 acetate (lacquer) and aluminum discs created during the 1930s through 1950s. Once the discs were cleaned, a physical assessment was completed and the audio was digitized. Unfortunately, some of the discs could not be transferred due to delamination of the lacquer layer. Approximately 15 % of the discs had palmitic acid residue on the surface caused by deterioration of the lacquer layer. Other discs were warped or had uneven surfaces, but data was transferable.
The first phase of the project produced master digital audio files, reference CDs, and MP3 files, which will allow cataloging of the materials and will make them accessible to researchers, scholars, and the general public.
The original discs were re-housed in acid- and lignin-free record envelopes and placed in appropriately sized boxes. The archives staff created special spacers for support. We are fortunate that the majority of the disc labels contain descriptive information which will assist us when we begin the cataloging phase of the project.
