Hi Jeffbert - long time, no see, but VERY glad to see you are finally going to make the book happen.
I have what might be a very viable solution for you. First of all, I worked for one of the big "vanity" presses in the USA - Vantage - back in the 80's (they are the company that got an expose on 60 Minutes!). The folks there were nice people, and it really was designed as a solution (back then) for people who wanted their research published. Folks who thought Vantage were actually going to help market the books were sadly mislead. I used to do covers and actually lay out the books. Fun job (didn't pay really well though) -
BUT - I'm going to suggest you check out Amazon CreateSpace
https://www.createspace.com/A friend of mine (she's a children's illustrator) has very successfully self-published a number of coloring books through Amazon. Here's her page:
https://www.amazon.com/Barbara-Lanza/e/ ... ont_book_1She said that it doesn't really cost anything - she supplies a pdf of each book and they are printing "on demand."
As for layout - some people can manipulate Microsoft Word and Open Office extremely effectively, but I personally have found both of them very frustrating. "Real" desktop publishing programs (like InDesign and QuarkXpress) provide tools for setting up things like indexes, sections of books -- but they are still not super-duper easy (I used InDesign to create a 250+ page book once with charts and maps and photos and an index and table of contents - and I'm an experienced graphic designer - but that was a BEAR to work on!
I find that Microsoft Publisher is much more like a true desktop publishing program (you can connect the text boxes, "jump" to designated locations, and set up layouts that are more flexible than is easily possible in Word).
I know I haven't been on the forum much over the past year but I'm still here and still very interested in this book of yours - Any questions you have and any help I can offer, I'm very happy to do so!
Speaking of the forum -- I'm not understanding where everyone went? Discord or something? I just figured it was the utter lack of creation of any new Astro Boy content (whatever happened to the reboot?)
So glad to know you are at the point of publishing, jeffbert!
