Not an elegant solution, but the Census Bureau's website allows you to interactively view Census Tract Maps. You can go to https://www.census.gov/data.html and select "Tables and Maps". Select the "Maps" Tab and then "year" button to set it to 2020 and the "Boundaries" button at the top of the map to get a right-hand menu to tell it to display and label Census Tracts. You can then Zoom to the area where you want a census tract map. Unfortunately, there is no way to download the map generated, but you can take a screen capture. I've attached a PDF of LA County. However, LA County has so many small census tracts that not every tract can be labeled. I didn't select any tract-level data to be displayed. Depending on what your patron wants to use the county-wide census tract map for, they might find this a useful tool. PS - Somewhere in the vast Census website, there might be exactly what your patron is looking for, but their site is not easy to navigate.

Unless there are other details on the PDF sheets he needs, I'd suggest your patron look into learning just a little GIS (QGIS) so he can make his own county maps from census GIS data. https://www.qgistutorials.com/en/<https://urldefense.com/v3/__https:/www.qgistutorials.com/en/__;!!C5qS4YX3!B36oxO-FaCKakNfLLwczcMng38VjMrnYKihiG-5Enfck5G20XOJlDARIptlfpdPp6uNtTErW10Oy2HomTRXKVbI$> https://data2.nhgis.org/main<https://urldefense.com/v3/__https:/data2.nhgis.org/main__;!!C5qS4YX3!B36oxO-FaCKakNfLLwczcMng38VjMrnYKihiG-5Enfck5G20XOJlDARIptlfpdPp6uNtTErW10Oy2Homf1kGYjE$> David Medeiros Geospatial Reference & Instruction Specialist Stanford Geospatial Center 650.561.5294 @mapbliss SGC website: gis.stanford.edu GIS cartography: bit.ly/giscart GIS email list: bit.ly/GISlist ________________________________ From: Maps-L: Map Librarians, etc. <[log in to unmask]<mailto:[log in to unmask]>> on behalf of Weessies, Kathleen <[log in to unmask]<mailto:[log in to unmask]>> Sent: Friday, October 21, 2022 11:23 AM To: [log in to unmask]<mailto:[log in to unmask]> <[log in to unmask]<mailto:[log in to unmask]>> Subject: One gigantic census tract map? Stitching PDFs? A patron came into the map library today wanting one giant PDF that shows the 2020 census tracts of a county. Starting with Cook County, Illinois. The usual Census website<https://urldefense.com/v3/__https:/www2.census.gov/geo/maps/DC2020/PL20/st17_il/censustract_maps/__;!!C5qS4YX3!B36oxO-FaCKakNfLLwczcMng38VjMrnYKihiG-5Enfck5G20XOJlDARIptlfpdPp6uNtTErW10Oy2HomdreqdD0$> reference maps carve Cook County into 6 large PDFs - thankfully all at the same scale. His fallback plan that he wants to avoid is taking the time to slice off the margins of each sheet and forcing the PDFs together into one giant PDF file. But he swears about a month ago he tripped across a website (which he can't find now) that allowed him to select several sheets and the website stitched them together for him. Does this sound familiar? He cringes at his next county of interest, Los Angeles County, because the many PDF sheets were created at varying scales and won't abut each other nicely at all without a whole lot of digital tomfoolery.
