title_body: Referencing cover, title, and dedication pages in ePub navigational TOC
upvoted_answer: I really know little about InDesign and less about desktop ebook readers for Macs. 
  
  But I know ibooks, and I'm guessing that the page numbers are calculated by the program. The TOC comes from the toc.ncx file inside the epub zip. Indesign probably auto-generates that from chapter titles. 
  
  On my title page I often link to parts inside the ebook, and even though it's theoretically possible for me to link back to it, I can't think of a situation where i would need to. 
  
  On most ebook reading platforms, the cover page is not listed in the TOC but if you go Page Back from the first page (or the title page), you can usually get to there easily.
