The PCC position on non-filing indicators has been stated on a posting
to the PCC list Apr.22, 2003:
"When MARC 21 was issued
in 1999 the method of counting non-filing characters was clarified.
That clarification resulted in a change in practice that the Library
of Congress implemented on February 20, 2003 (http://lcweb.loc.gov/catdir/cpso/nonfil.html
). Since the method
of counting non-filing characters is a MARC 21 convention, presumably
the aim of all PCC participants would be, sooner or later, to follow
that convention if they haven't been since 1999. When to make the adjustment
needed to follow the convention as currently stated in MARC 21 may be
influenced by considerations related to local systems or to the bibliographic
utilities. LC kept both OCLC and RLIN apprised of its schedule and of
the details of its implementation and both have indicated that they
are currently able to handle the old and new conventions."
"In cataloging a PCC
record today, follow the current MARC 21 convention for counting non-filing
characters if that convention is supported by the local system or bibliographic
utility one is working in. If that is not possible, follow the convention
that is supported at the time of input. The ultimate goal will be eventually
for all to follow the MARC 21 convention."

On Voyager, neither use of
the current MARC 21 convention nor the obsolete method will affect retrieval.
For all new records created
in Voyager or RLIN, begin using the new method of counting non-filing
indicators. Apply the new method whether or not the record is coded
It is not necessary to update
the filing indicator in source copy records using the pre-MARC 21 counting
method; MARS processing is expected to update the nonfiling indicators
to the MARC 21 standard. Copy catalogers should be aware of the new
standard and not "correct" records following the new standard
to pre-MARC 21.
Two relevant documents may
be accessed on the Bibco page.

memo describing the LC implementation, with examples, in PDF format:
