Our story starts in the City Archives, where the collections present challenges…
The first of which was
ORGANIZATION. With images stored in boxes based on the city unit they
represented (Streets, Schools, etc.), finding any particular image was a significant
challenge.
The second was PRESERVATION. The oldest negatives are combustible, and newer ones are prone
to warping.
The third was ACCESS. To access an image, a visitor would have to go to the archives and have a valid research reason for entrance. Approximately 100 people per year
did this.
Certain images and/or photos on this page are the copyrighted property of 123RF Limited, its Contributors or Licensed Partners and are being used with permission under license. These images and/or photos may not be copied or downloaded without permission from 123RF Limited
The last was FUNDING. Addressing these challenges was unlikely to be an inexpensive endeavor.
