Notes on the Small PDF download. After the downloading is complete, the PDF will open and display in a new tab. The download takes 1 to 2 minutes because it’s very large, at 532 Mb. You can confirm it’s downloading by looking in the Downloads screen of the browser. After the download is complete, it may automatically save to the smartphone or PC memory, but it may not. The file may need to be “saved to memory” manually, or the device may discard it. Different devices handle this differently. This file is intended to be kept on the device, making access to the website unimportant. The Small PDF is a good single file substitute for the “100% with titles” full set A, that might be used instead.

The picture above is a sample of how a few Salt Fork pages display on a phone. This is a view from the middle of the small PDF file. In the single-column PDF, you can zoom in to each picture to see more detail. The base picture size is 2500 x 3300. The Medium and Large PDFs have a higher picture resolution, and are listed as Downloads on the OHM Downloads webpage. They are 1005 Mb and 2000 Mb respectively.

Download the Small size PDF. This is a new single file, voice-searchable, medium-resolution, all-in-one PDF that is downloadable as of 9-1-25. This contains the 9-1-25 full set, 1546 pages total. On a smartphone the voice search works well. All of the small features on the very busy maps like the Wayne topos can be seen, but in a lower-resolution way. The searchable terms are mostly the logical titles that you see at the bottom of the pictures. This includes the area name, usually the full title, including for example, “Two mile”, “Four mile”, “Index”, “Road maps”, and “Ohio sunrise”. The Small size here is 532 Mb. There are some pointers on using the PDFs in the Technical notes webpage. The filename is “OHM 0925 pdf Small 532 Mb searchable.pdf”.
