The record book (5)
I believe the answer is:
album
This clue is a double definition.
'the record' is the first definition.
(I've seen this before)
'book?' is the second definition.
(album is a kind of book)
(Other definitions for album that I've seen before include "Photograph/stamp book" , "Book for stamps/photos" , "A music record or a book of photos" , "LP, perhaps?" , "Pictures" .)
