Whelp, I've merged Dice Rule! Book 1 and Book 2 into a single document. Book 1 housed Chapters 1 thru 7. Book 2 housed Chapters 8 thru 12. I kept two books because it was easier to navigate the document in this fashion (both were under 100 pages). I'm now facing a 189 page paper golem!
The merge is a significant step forward to publishing, but there is still a long road ahead. My next step is what I call the "SNR Stage". SNR = Search and Replace (that lovely function of MS Word). While working on the books I kept track of any key terminology, abbreviation preferences, changes to rules, clarifications, etc, and logged them in the back of the book. For wegsample, is it "Cold Roll" or "Cold roll", and "Per Level Bonus" or "PL Bonus". Little stuff like that that ripples through the book. I also have a list of frequent typos to scan, like "their" for "there" and any place that three successive blank spaces appear. Real exciting stuff!
Post-merge I scan the full-bodied document from the top, going down the list one by one. It's an arduous and boring process. A complete necessity for overall synchronicity. Some folks might even call this step "copy editing".
This step let's me move the oversized golem to the door to get it on its way.
Let's hope the dang thing doesn't topple over on me in the process!
