I'm afraid that I have made a discovery about the printing process of Lulu that has me concerned for this project.
After properly scaling the first volume's word document into a PDF, I have found that the word count will exceed the maximum limit of a book to be printed on Lulu.com. This will require the first volume to be split into two books, and this will only grow with later volumes as they are longer.
I will see what I can do to make this work, but the process is proving to have a few curveballs thrown in. If anyone is still interested in purchasing a copy of each half, please let me know.
