We were just given some 1:50,000 scale AMS/DMA maps of Illinois. But some of them are actually 1:25,000. I didn't realize that AMS/DMA published 1:25,000 scale maps. Are these just a minor variation in the 1:50,000 series, or are the 1:25,000 scale maps considered their own series? I have the OCLC record for the 1:50,000 scale series and it doesn't mention a dual scale. I haven't found a record for the 1:25,000 series, but it could be out there. I checked the DMA 1:50,000 scale index map (the ones that we have between 1982 and 1994) that USGS published but they didn't solve the issue. Are these two scale really the same series, or are they really separate series? Anyone found an OCLC record for the 1:25,000 series?
