All of my reports are done through the Reports > Publisher feature. I think there are some minor improvements that could be made, but it is a strong way communicate.
I have developed a typical sequence for my chapters, and standard text for chapters such as Preface, Acknowledgements, etc. That info is stored in a "template" book, from where I can copy & pste into the next new book I'm developing. I call it a template, and here's where an improvement would be nice: In programs like Excel, I can create a template worksheet and do a Copy or SaveAs to start a new project. In RM, I have to manually recreate a book for the new project, and manually copy & paste the info from my template to the new project. So the template is an archive of my ideas, but isn't a true starting point for the new project.
I'd say that my typical Genealogy book has about 2 dozen chapters (including indices). I've created some books with 4 score of chapters. I've come to the realization that my typical reader seems most comfortable with books under 300 pages, which sometimes leads to carefully considering omitting some of the additional Ancestor and/or Descendant narratives that I might like to include.
I also have a book template for a Scrapbook Companion, which prints all of the supporting documents. This is pretty easy to do, but not particularly elegant in RM. I create a dummy individual called [scrapbook] Surname, and use a custom fact called Scrapbook to create a list of the attached media (1-generation narrative), and the set of images (person scrapbook).
For my current project, for one of my cousins, I am also going to include a third volume of Pedigree charts. Within the Genealogy book, I normally include only 8-10 generations of pedigree charts. By splitting it into a third volume, I will be comfortable extending that to 20 generations or so. This volume will also get Name and Place indices, but not Endnotes nor Bibliography.
One major advantage of this scheme, is that once I've set up a book project, printing an update after additional research is quite simple -- the main effort of organization is already done.
From the Publisher book, I generate PDF files to share. Sometimes I have a local print shop produce one set of books for my reader, but the PDF files give the reader that option.
All of my books contain a notice reminding readers that there is much sensitive info compiled, and requesting that they do NOT post the book publicly.
