Book a strong man (5)

I believe the answer is:

atlas

I believe this is a double definition.

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

'a strong man' is the second definition.
(thesaurus)

(Other definitions for atlas that I've seen before include "The first cervical vertebra" , "Collection of maps" , "Titan who supported the heavens" , "book of world records?" , "world record?" .)

I've seen this clue in The Irish News and The Globe and Mail.
