Curious to see if others have had this problem as well On Mon, Feb 12, 2024 at 7:35 AM Brendan Whyte <[log in to unmask]<mailto:[log in to unmask]>> wrote: Hi all, I've been trying to download the Iowa 24k topo index from the USGS site so I can index our holdings. But whether I open it directly from the USGS store, https://store.usgs.gov/product/54160 or download the pdf and try opening it in Acrobat, Chrome or Edge, I always get a "corrupted file" message. Is this just me, or is the file corrupted for all of you stateside as well? I have found the jpg scan at https://www.yellowmaps.com/usgs/topomaps/index-maps/24/ia.jpg but the resolution is a bit low for my needs. And the pdf booklet index at https://publications.iowa.gov/22843/1/Iowa%20index%20to%20topographic%20and%20other%20map%20coverage.pdf is neither a single sheet, nor does it have the sheetnames on the map. Would someone kind be able to point me to/send me (dropbox etc) a decent scan/pdf of the index? Any help much appreciated! Thank you, Brendan Whyte National Library of Australia
