Alice, HelenJane, Ilene, et. al...
Here at the Illinois State Library (a regional depository) we collect our
topos in this fashion:
For Illinois we have 2 copies of all the current 7.5s, and we collect/keep
as many copies of the old, superseded ones as we can lay our hands on
(within reason). This set is all but complete. We also have the DRGs & DOQs.
For the six states that surround Illinois we retain 1 copy of the current
and also collect/keep copies of the superseded. These sets aren't as
complete as our Illinois set.
For the rest of the country we keep only the current 7.5
As to the old 15s, we have a complete collection for Illinois, although a
few are only available on some pretty crappy microfilm. We also try to
collect/keep old 15s for the six states surrounding Illinois, but this
collection is our spottiest.
All our topos circulate, regardless of age. Naturally they get heavily used,
but luckily almost all of the frequent users realize the value of the maps
and take very good care of them. Nevertheless I try to "persuade" patrons to
let me make copies (we can copy in both b&w and color) and this seems to
work well for all of us. The 15s and most of our old 7.5s are encapsulated
and de-acidified when possible. And the current 7.5s are stored separately
from the superseded. Illinois topos also have a separate storage area.
As for records we have checklists for both current & superseded Illinois
topos, 7.5 and 15, that can be found here:
http://www.cyberdriveillinois.com/library/isl/ref/lstopo_quads.html
And there is a checklist for our historical topos of the six states
surrounding Illinois. It can be found here:
http://www.cyberdriveillinois.com/library/isl/ref/historical_topos.html
(We also have these checklists in paper if anybody's interested)
Finally the current 7.5s are cataloged, while the 15s are not.
Any other questions? Drop me a line...

Alice (and others)-
We keep all of our U.S. topos, older editions, too. In general, it seems
to be useful to patrons to have all editions of the quads available.
In response to HelenJane's questions: we circulate topos that are newer
than 1949. Pre-1950 topos do not circulate, although we do allow them to
be photocopied. If 1950 seems like a random date, it's just the date we
chose (several years ago now) b/c we thought maps prior to this date
would be impossible to replace if lost. Our maps are filed by scale, so
all the 1:24,000 topos are alphabetical within states and then in
chronological order, with the newest edition on top. Older topos (i.e.,
pre-1940 1:62,500, 1:100,00, etc.) are in other drawers, at the end of
each particular state. We are about 99 percent done w/getting complete
records in our online catalog for the 1:24,000 quads for the entire U.S.
Although there are not online records for our older quads at other
scales, we do plan to someday have these in the catalog, as well.
Hope this helps. We're very interested in what other libraries are doing
w/their U.S. topo collection.
