I was just wondering if there was any general consensus on what are considered text pages where writing and such isn't allowed? The main book text obviously. In other forum posts, I saw everyone generally agree that the book index also shouldn't allow it, but nobody had a problem with someone signing over their name in the acknowledgements section (maybe because nobody actually reads that section, or because they viewed it as similar to an author signature on the title page?). PBS says the title page is okay. What about the publication info page, table of contents, notes, introduction, or other supplementary material sections?

In my view, I make it simple, and don't think there should be any writing anywhere on any text page unless it's a author signature or something equivalent that is allowed by the rules, since those are pretty much always on the title page, which does have text. But, if there is a consensus on other exceptions to the rule, I would really like to know about it.

IMO, Text pages are story pages, or other pages that are integral to understanding and using the book. Like  a Table of Contents or an Index, or the Introduction or the Preface, The Introduction and the Preface are either written by the author of the book, or perhaps by another writer who is introducing and/or critiquing the book. Its part of the book and if it is by a writer other than the author, is often credited on the book cover. So, it falls firmly into "text pages", that someone who wants the book would expect to be able to read clearly without writing or highlighting.

The title page, copyright page, review pages, dedication page, etc are not text pages in my opinion. Neither are advertising pages in the back of the book. Or, even the excerpts of "coming in the future books" that often follow the story

So, I don't know if I would call it a consensus .... but that's what I think.

I completely agree with Sara!

For me it's anything but blank pages, title page or TOC.

I agree with Sara.  I think marking a book RWAP because somebody wrote their name & the date on the teaser or book review page is the very height of nitpicky:P  I can understand being hesitant about sending one like that, but I tend to think that someone who would RWAP a book like that is being pretty fussy - to say the least.  Many a UBS & library will stamp, mark, & write on these pages, and nobody thinks much of it, so I can't see why someone writing their name & the date on them should be any different.  Just MHO.
