Warning about trying to find digital copies on Hathi Trust. Sometimes you will search for a source, but what they return will not contain what you are looking for, or not contain the best source of what you are looking for, however there are other sources which will point to the Hathi Trust, even though Hathi does not retrieve those links for you. Search by author, and you will find internet pages which link you to source material.
I got two of my sources for my current work on Confucius by this second method. So, I will be making a couple of ebooks one can search the internet and not find a good copy of in this work I am calling Karaoke Confucius. All work will have been through new image processing, even some through several passes of Photoshop.
All work will also come with audio book version.
