Hi Brendan,
Cataloging a map series is always a challenge to map catalogers. Should they catalog the map at an individual sheet level, or at collection level? Cataloging at collection level saves time, however, cataloging at an individual sheet level provides better access in finding an individual sheet. In your case, I think the best solution is to catalog the US 24K map series by state. However, when you catalog them by state, list all the sheet names in the 505 field. This will allow a person to search any individual sheet from a catalog record and also find out all the sheets you have on that state from one catalog record. Of course, you can link the scanned map index to the catalog record to give coverage of that series by state.
A few years ago, I was making a decision on how to catalog the AMS 1:25K scale map series on India and Pakistan. We made a decision to catalog all the map sheets at collection level and added all the sheet numbers and names in the 505 field in the catalog record. This has allowed us to link (https://catalog.princeton.edu/catalog/99125464907006421) four expressions (paper map, scanned map, georeferenced map, and mosaic map) of the same map on one catalog record. Now a patron can find not only the paper map record from the above catalog record link, but also view and download scanned and georeferenced maps, and also view a mosaic map (all the sheets together). This mosaiced map can be added to any GIS software packages that can read Web Map Tile Services or XYZ Tile Services. I think cataloging the way we have done might give you more options in the future.
Thanks,

Subject: Indexing US 24k series... feedback please
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 record https://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!
