Sign jacket of racy books here? (7)
I believe the answer is:
library
'books here?' is the definition.
'library' can be an answer for 'books'. I am unsure of the 'here?' bit.
'sign jacket of racy' is the wordplay.
I cannot quite see how this works, but
'sign' could be 'libra' (sign of the zodiac) and 'libra' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for library that I've seen before include "Book archive" , "Building housing book collection, may be public" , "Book repository" , "Bibliotheca" , "Book room" .)
