Archives overlapped houses? (9)
I believe the answer is:
'houses?' is the definition.
The definition and answer can be both man-made objects as well as being plural nouns.
Maybe they are linked in a way I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for libraries that I've seen before include "They house books" , "Book depositories" , "facilities for readers" , "Reading rooms" , "Collections" .)
