 Brendan,
May I ask what you mean by "AMS" maps in your U.S. topo collection?  Looking at your Maryland set (my state), you indicate that purple is for maps from both AMS (1:25,000) and USGS (1:24,000).  I work with the map collection at the University of Maryland library - we have almost all the USGS 1:24000 maps for the entire U.S., but only a few state collections (most incomplete) of the 1:25000 maps.  Both the 24K and 25K maps were produced by the USGS.  We have sets of "AMS" maps, but they were Army Map Service maps mainly of countries in Europe, Africa, Asia, etc. I believe our library received those AMS maps (mainly older maps from the 1930s-50s) because we are a depository library entitled to receive publications from the U.S. Government, and those older Europe, etc., maps were 'left overs' from the World War II era?  Thanks!

  Hi all,
After years of procrastination, I have begun indexing our US 24k series (very incomplete... we stopped collecting these when an exchange programme with USGS ceased 20-30 years ago)I have made an overall US map showing which states have been properly indexed to date, and attached this to our catalogue recordhttps://catalogue.nla.gov.au/catalog/6855508, along with coloured-in indexes of each of the 19 smallest states. 
The plan is to work my way through the remaining 30 states in 2024.... wish me luck!
Please let me have any feedback on what I have done so far.(once you've opened the US index, click 'browse this collection' in the breadcrumbs to see the individual state indexes)
What have others done in the way of online indexes for the series?We have never even considered cataloguing the sheets individually... but I guess we could have done individual records (and indexes) for each state set, and linked them with an overall parent series record similar to our existing record... but that's nevertheless more work for the cataloguers.
Compliments and criticism most welcome before I embark any deeper into this project...
Merry Christmas!
