I agree with all who do not use 'true' SuDoc for filing this series. The SuDoc stem, I 19.81: is the same for each state, first of all. Then a number is assigned following the colon, that is nowhere to be found or deciphered from anything on the sheet! A couple of respondents mention using a modification of the classification, I 19.81:State/sheet name/date. I have followed this practice, although this is really for record keeping and retrieval out of the catalog.
Likewise, it is equally meaningless to assign LC classification to them. You wind up with the number for each state, s24 (for the scale for a series), and you have to do something for each item to identify it from the others. That information is already on the sheet, as mentioned above.
You could really get away without assigning anything to them. You have the state name and sheet name and dates on each sheet. Even if you have one state or a few, you have a big enough set that they need nothing else to distinguish from other maps and sets. They are probably the single largest part of your collection.
In other words, the work has already been done on the map. You just decide whether you want them in alphabetic order by state name, or geographical/numerical by state according to LC class. And even with a classification system, you still have the arrangement within each state, probably by sheet name. The system used doesn't help there.
Either way, it's easy-peasy.

I am trying to find the names of larger size libraries that are cataloging and filing U.S.G.S. 7.5 minute series topographic maps using the Superintendent of Documents classification system. This system has advantages, but there are also disadvantages and problems.
I would like to find other libraries using the Supt. of Docs. number so that I can learn how they help people make use of their collection.
Cordially yours, Thomas Lindsey
P.S. for Valerie Glenn (formerly of UNT): The Fort Worth Public Library is dropping its depository status. It is working with Texas Tech and the University of North Texas to transfer as many documents as possible.
