"Thanks for the information.  I have to doublecheck an Ohio library catalog again, but I think that I have found one that does.

The system became complicated in 1999 when a cutter code for national forest or national grassland was inserted in front of the quadrangle number on any map that has a part of a national forest or national grassland.    I have compiled a list of about 100  Cutter   codes.  It makes filing "very interesting" if you file by including the Cutter code, instead of ignoring it.

Here is a record from our catalog:

I am trying to write a guide that explains how to find a map in our drawers.  It is not an easy task.    thanks for your help.  Tom Lindsey U T Arlington Library"

Thomas (and Valerie),

My bet is that you will find relatively few places classifying, and
particularly filing, their 7.5-minute topo sheets using SuDocs, but
I'll be curious to find out. I personally cannot think of a map
collection I've visited that didn't file the sheets alphabetically by
sheet name under a G-class number either for the U.S. as a whole or
subdivided by state.
