Subject: Glass plate negatives
At the Music Division of the New York Public Library we have retained 200 glass plate negatives from over 1,000. We have not found the physical negatives to be as important as their content (to our patrons) and therefore have made service copies available instead. Those we have chosen to retain are stored in individual side-seamed acid-free envelopes, in upright Hollinger boxes. We check them once a year for signs of deterioration or mold. These negatives are keyed to the service copies and are available only to qualified researchers.
