Book with maps (5)
I believe the answer is:
atlas
'book with maps' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for atlas that I've seen before include "Ballistic missile" , "Book of maps - fifteenth satellite of Jupiter" , "Titan compelled by Zeus to support the sky" , "Titan with a fearsome burden" , "A geog. book; N. African range" .)
