My wife's Uncle printed up a vanity run of about a hundred hard copies of his memories of his experiences flying 50 combat missions in WWII as a B-24 navigator. His book is more about the training pipe line and life in the squadron than it is about his actual combat missions. He does describe five combat missions in detail, including one ditching that should have killed him and a couple more where he was really lucky.
He passed away shortly after the book was printed.
I thought about it a lot and decided that I didn't want this book to die with him, so I
published it on Amazon.
Nobody could find the electronic copy of the book, so I had the book scanned ( ~$100). I made an editing pass through the resulting word document and caught about half the typos.
I hired an
editor/book designer for $350 through
Upwork. She designed the eBook, including cover artwork. She also caught most of the remaining OCR anomalies. She worked quickly and was a pleasure to deal with.
Frankly, Uncle Robert's book really could have benefited from a professional editor, but he didn't want one so we didn't modify anything that he wrote.
Once the designer had the final '.mobi' file done, I uploaded to Amazon via their Kindle Direct (
https://kdp.amazon.com/ ) program.
Our ISBN number cost $125. Amazon doesn't require it, but since I did this so that a hundred years from some kid in a virtual reality library can read about the greatest generation, and you need an ISBN number if you want your book to be searchable outside of Amazon.
I haven't promoted it beyond mentioning it on a couple of web forums. I think I'm getting about $75/month from it. I've recovered my costs and any future revenue will be donated to a scholarship fund for his unit alumni association.
There are several good writers here, I think any of them, and we know who you are, could make Uber driving money by publishing an eBook.
I did this DIY, but there are services that will do the grunt work for you, and put your book on iTunes, Barnes & Noble, etc.
I had my book scanned by Bookbaby (
http://www.bookbaby.com ), I think they are decent and can do any part or all of the publishing process.
I'm working on an Audio Book version. I'll get it done, but it's slow going. It takes me about about two hours to get 15-20 minutes of audio that has a chance of passing
Audible's QC process.
