In the library to which I referred (University of Utah Marriott Library),
the book and map carry the same index number.  The library employs the
Library of Congress system, so I don't think the numbers will be changed in
the near future.  This reference system will help to avoid the problem that
Andrew Cook identifies.  The online card catalog indicates that there is a
map stored at a different location, or, the user will know instantaneously
that the map is somewhere else because the pocket is empty.  For a person
unacquainted with the filing system, it takes only one time asking the
librarian what happened to the map to be introduced to their storage
location.
 
Incidentally, I am not a map librarian, but a map library user.
