album

I'm a little stuck... Click here to teach me more about this clue!

'book' is the definition.
(album is a kind of book)

I don't understand the rest of the clue.

(Other definitions for album that I've seen before include "A music record or a book of photos" , "Book of blank pages for collectables, memorabilia etc." , "Pictures" , "Recording; book" , "Music record or photo book" .)

I've seen this clue in The Telegraph.
