Here is the current selection of digital HOLC maps I have available. I oversaw the digitization of the majority of these and make them available for public use. In addition, I include a few maps for other cities (also available through ARC, the NARA catalog) that were scanned at medium resolution. These documents were produced by the federal government and are in the public domain, so they can be used by scholars, students, and the general public. Be sure to give adequate citation of the original sources and this site. These have been scanned at high resolution, but many of them are linked here at a reference size (4000-8000 px on the short side) great for online viewing, but not as good for printing. If you are interested in a larger or smaller version, please let me know, as I have alternate sizes in storage.
