The Earth Sciences and Map Library has reached a technical
processing milestone. Several years ago work was begun on
converting holdings for our largest set of topographic maps to
machine readable form. This map set, produced by the U.S.
Geological Survey, contains more than 60,000 sheets covering each
of the U.S. states. Since the map collection retains superseded
editions, our holdings are significantly higher.
Some of you may remember DOC2 cards. These are 3 x 5 inch orange
cards gridded off in boxes that contained all of the holding
information for this very large set. The cards originally filled a
large five foot high card catalog to capacity. Due to the sheer
number of holdings and the alphabetical nature of the v/c
information, it was not feasible to add all holdings to a single
Gladis record. Instead d-level Gladis records were created for each
sheet area. This enabled inventory control and allowed for
automated circulation.
Keying for this project was begun several years ago, before all of
our various moves and several states were completed. However,
credit for the bulk of the work goes to Traci Penrod (LA-III), who
for more than two years has diligently keyed records, added
holdings, and bar coded all the maps until at last all those DOC2
cards have disappeared. As projects go, this was certainly a
daunting one and ranked high for tedious repetitiveness. Traci
never complained once, but we all know she is glad it is behind her
now.
For awesome statistics: Between January 1998 to January 2000,
Traci created 47,202 d-level Gladis records, added holdings and bar
coded 72,798 maps. Great job Traci!
