Does anyone out there have a count of how many quadrangles make up the
complete set of USGS 7.5-minute topographic maps?  We have just finished
"reading" our 44 drawers of these and are half done marking new index maps.
 
We want to get a more accurate handle on how many we actually have, without
having to physically count them all.
