@Cedar Lake asked me about the process of how I create the "books" out of the stories so that they have cover pages, table of contents, etc. My semi-simple answer is that I use MSWord.
You open a blank document: File >> New >> Blank Document
Add Cover Page: Open blank document then go to Insert >> Cover Page (Using the drop-down menu there are several preformatted options. You can create your own but I generally use the preformatted ones and then change them up like using my own picture, change the colors, etc.)
Add Table of Contents: Go to your next page. I generally do this by forcing a page break (Ctrl + Enter). At the top of that page ... References >> Table of Contents (Then use the drop-down menu to pick your style of TOC.)
How you get the TOC to update so you don't have to do it manually is that you make sure you format your chapter numbers as a Heading and you do that under Home and you see Styles to the right. Just highlight your "Chapter #" with your mouse and then hit Heading 1 or which ever style you want. To update your TOC, just use the update feature on the TOC or on the bar under references where you picked your TOC style.
Page number is something else you can add and there are a bunch of different styles of those as well. That's Insert >> Page Numbers. Use your dropdown menu and pick your style and location. The TOC works without the page numbers being inserted visually but it looks better in the final product.
The pictures, footnotes, endnotes, etc. is just a matter of formatting. I'd need to have a specific thing you want to do to explain it otherwise we'll end up with a MSWord booklet right here. LOL.
Anyway, that's the long and short of it. Hope this answers your question(s).
Oh, and how I take it from the MSWord document to a .pdf is easy peezy as well. When you go to print something, instead of printing it to a specific printer, there is an option in the drop down menu to print it to:
