Book with many legends (5)
I believe the answer is:
atlas
'book with many legends' 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 "Legendary weightlifter" , "Asian satin" , "One of the Titans" , "Titan compelled by Zeus to support the sky" , "N. African mountains; a Titan" .)
