Now to get it to work, so far I am not having much luck.
Would it be possible to give me the correct expression to copy and paste? It is to remove the title on the even pages, the author on the odd pages and the page number (just as the number: 1, 2 etc.).
I don't know if it makes any difference but I am using Calibre version 0.7.25.
I am also wondering if I am putting it the correct place: Structure Detection, header regular expresion, with a tick in remove header.
Sorry to be a pain!
