Reply To: Book overlay

By "book overlay" do you mean the book jacket?

If that is the case, there is no rule for transcribing a book jacket.  In my experience, the book jacket is not included in the transcription.  If you are required to include it, it belongs in the p-pages with material from the back cover, inside front cover, etc. with no print page number.  A tn would explain its location in print.
