NAR09-RD-10017-09 Digitizing Outdoor Advertising Final Report

Digitization equipment
In addition to great project staff, our strategic purchase of a Zeutschel 14000 A2
overhead scanner (rather than the planned Epson 10000XL flatbed) enabled us to
increase our digitization throughput. Where the Epson scanner was estimated to take
around six minutes per scan, including time for material handling, quality control, and
generating derivatives, the Zeutschel averaged approximately two minutes per scan
for the same work.
Contract digitization services and shipping costs
Outsourced slide digitization proceeded at the expected pace. Even though we
adjusted our original digitization plan, sending smaller batches more frequently in
order to conduct quality control on each batch as it was returned, our timeline for
completion of the approximately 12,000 slides was unaffected. The unplanned
increase in costs for contract digitization did not affect our total costs, due to the
faster digitization pace afforded by the Zeutschel and the efficient work of our
Digitization Assistant.
2. Publication with Metadata
Metadata cleaning began during the digitization phase, and continued during
preparation of the collection for publication. Unexpected infrastructure development
and staff turnover altered original plans to publish the collection in batches. Instead,
publication was postponed until work on a new digital collections discover and
access application was completed. The ROAD 2.0 collection
(http://library.duke.edu/digitalcollections/outdoor_advertising/) was published in its
entirety only one month later than originally planned.
The project team established goals for metadata cleanup to enable a more effective
discovery interface upon publication. Digitization Assistant Rita Johnston focused on
creating new records in cases where multiple items were described in the same
record. She has also refined records that had been given a “Miscellaneous” subject
designation and corrected company names where values were inconsistently
assigned.
Publication of the images with the ROAD database metadata required cleaning of the
metadata to correct errors and to enable item-level searching of images, and
mapping of the existing descriptive values to a more generic and discoverable
schema based in Dublin Core. This modified Dublin Core schema, which we refer to
as AdCore, includes additional descriptive values mapped to Dublin Core elements. A
list of these new values can be found in APPENDIX 1: AdCore Metadata Schema
Additional Elements.
3. Assessment of Use
To assess the use of the ROAD 2.0 digital collection, we developed and conducted a
web-based user survey. A copy of the survey can be found in APPENDIX 2: ROAD 2.0
