Product Page: Flowing Text / Pages
Everything seems to be going swimmingly, EPUB up and running... I noticed on the Lulu Product Page down at the bottom there is a small section:
Flowing Text / Pages ... that is listed as Flowing Text.
..and, luckily, I formatted the whole thing for flowing text so I am currently sleeping nights.
However, right at the beginning of the EPUB formatting process when I copied the whole book from MS Word and pasted it as text into a notepad file in order to start over with fresh Styles in MS Word for flowing text I also made a copy of the .txt file for a future setup with 'Pages' in mind. With over 40 illustrations in the book I found it interesting and had a deal of success with creating bookmarks for the illustrations and reverse bookmarks to get back to the point in the book where you left off reading . . . all illustrations stored at the end of the book, of course, one to a page.
Question is, now that I have an EPUB with flowing text, what is the Lulu situation regarding a separate EPUB of the same book formatted for pages..? I didn't notice anywhere in the Lulu Project Setup that mentioned it.
