Jon, They borrowed our master set of Colorado topos for the scanning project. You can see our stamps on a lot of the Colorado topos. But since they did that, we have gotten a few new-to-us ones. Who are you sending the maps to? What's their contact info? thanks, Christopher J.J.

USGS 7.5' topos For those of you who have per-sheet bib records: Have you reconciled what you have versus the USGS historic topo scanning project? We don't have item records or bib records for individual sheets here at UCSB, but we do have a strong inventory that was used as the basis for the USGS's inventory of California quads. In the end, there were ~300 that they didn't have in their own collection (which we have shipped off to them for scanning now) and they had about the same number that we did not have here. There are numerous gaps in the 15' series at USGS. That's another project to crack open sometime in the future.
