I'm a little confused about correct practice for the new 655s.
I'd be grateful for anyone's thoughts on the following:
[1] It looks as though LC is insisting on including a
655  0 Maps.
(see, e.g., OCLC 664808196) in the absence of a "thematic" 655. The
implication is that from now on all map records _must_ have a 655. Is
this right? (But see OCLC 664808195 for a counterexample.)
[2] "Road maps" does not appear in the list of 655s I've seen, but see
OCLC  664808197 which has both
655  0 Road maps.
and a
650  0 Roads #z[Place name] #vMaps.
Is this right? (Note also OCLC 664808194, which has a
655  0 Roads maps.
.) Other recent LC records (e.g., 664808196, mentioned above) don't try
to get "road maps" into a 655 at all.
Is there a "correct" practice here?
Thanks.
