I am new to the world of map cataloging and have a pretty basic question…

Our library has a map collection of about 5,000 maps which we they have
just now decided to catalog. They are pretty much split evenly between
topographic maps and geologic maps. I am starting with the topographic maps.

In reading the LC Map Cataloging Manual and ALA Cartographic Materials,
I see that maps are typically classified using the Class G schedule of
LC. However, since we use Dewey for all our books, I am unfamiliar with
the complete procedure for creating LC call #s. I understand the concept
of the basic classification number and the addition of a subdividing
cutter. For example, I know that the classification for a map of the
Buttonwillow, CA area would be G4364 .B95. I also know that the USGS
quadrangle names are not authority-controlled.

So, what happens when you have a quadrangle for which there is no
corresponding cutter in the schedule? For example, I have a USGS map of
the Stevens quadrangle in Kern County, California. This area is in the
middle of the oil fields, and Stevens is the only named place shown on
the map. Is it “legitimate” to extrapolate a cutter that falls between 2
other cities shown in the schedule? In this case, it would be between
Stent (.S893) and Stinson Beach (.S896). I also came across a map
quadrangle that is called “West of Elk Hills” which again doesn’t show
any identifiable natural feature or town.

I’m just trying to get a better understanding of how this works so that
I can work with the librarian in charge of this collection to decide the
best way to classify these.

Thank you
