How to know the number of pages of a book? (¿Quién asesino a Manuel Rodríguez)

[Pablo]

I added a new edition of this book: https://www.goodreads.com/book/show/5...

I added the isbn too that came inside the book, but I don't know what I'm supposed to write there.

I can fix it myself, but I don't know if I have to fill it with the last page number wrote in the book (274), which is the bibliography, or the very last page (index), since the two latter are empty.

This is the isbn in case is useful: 9789569977794

Sorry, I just found this:

In this case, the latest "printed page number" is 274, plus index and empty pages. Is that what I should use?

Pablo, use 274 + the index, ignore the empty pages.

276 then. Thanks!
