Crossword Genius

Book a sailor brought back (5)

Ross

I believe the answer is:

atlas

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

'a sailor brought back' is the wordplay.
'sailor' becomes 'salt' (salt is a kind of sailor).
'brought back' shows that the letters should be reversed in order.
'salt' backwards is 'tlas'.
'a'+'tlas'='ATLAS'

(Other definitions for atlas that I've seen before include "Giant" , "travel book" , "Album of maps" , "I carry a huge weight" , "used for maps" .)

I've seen this clue in The Telegraph.
