Recently, I edited (with the help of Clay and Mat) and updated a version of the Thomas book, and retitled it Thomas!. I finished the first version of the book by the end of 2019, and have just received a proof copy.
Overall, I am pleased with the result. I'm planning on changing a few things before moving on to making it available to my family more widely, but in general I feel like it turned out well.
I used Lulu's self publishing service, and I would very much recommend it. All that was required from my end was designing the cover and formatting the book into a pdf, and then the rest was taken care by Lulu. The whole process, from uploading the finished document to having the book in my hand took less than 2 weeks.
The book is largely the same as the pdf version that I put out in January of 2019. There are a few added biographies to the biographical section, an afterward, and more images and census records included, as well as the updated formatting. The main excerpts from the three genealogy books are the same.
