My personal opinion is: If information doesn't have a direct bearing on the story, there is no problem with putting the information at the end of the book. I see no problem with placing the copyright, acknowledgements, cast list, and dedication pages at the end of the book. If a foreword, prologue, or introduction page contains information the reader should be aware of before reading the book to understand the storyline, then I would place the information in the front. If the eBook provides links for jumping to a defined target or uses pagination and allows the reader to go to a specific page, then I would place the table of contents page, if provided, in the front.
Generally, the TOC is automatically generated, and is easily accessible from anywhere within the document. However, generally when you open a book, the very first page in the cover (natch), and then many of the 'ebook only ebooks' seem to jump directly into the story.
I guess my question is: If I move the 'front matter' to the back of the book, then what do I do with the traditional 'back matter'? Do I put it in front of the 'front matter' (since it's more directly story related), or do I put it behind the front matter?
There are some obvious exceptions, of course. Prologues are generally part of the story itself, while a Preface or Foreward would remain in the 'front matter' section. Similarly, while most of the 'back matter' should go ALL the way in the back, the Cast of Character (since readers are more likely to look it up while reading the book), should probably be kept near the story itself.
By the way, this all came up because I had problems with epubs displaying correctly on my Apple Ipad. SW on the iDevices have a history of places extraneous blank pages at the start of the book and before each chapter. This last time, the 'extra' blank pages numbered from 4 to 6! I managed to whittle them back down to only 2, but I decided the best way to minimize them is to simply shove them all in the back, so readers wouldn't have to wade through so many 1-page front-matter chapters, each surrounded by 2 blank pages.
It's a kludgy solution, at best, but it does make it easier to deal with. It was only while searching for how other ebooks dealt with it that I noticed most of Mine all start with the story, but they had no traditional back matter to contrast with it. :(
