At NSDP, we have cataloged several publications which are delivered
by fax.  We have treated them the same as print publications with a note
about their being transmitted by fax.  We would not consider a change
from a print publication delivered by U.S. mail to a print publication
delivered by fax to require a new record.  Only the delivery method has
changed.  A faxed publication is not a reproduction since there is no
original publication which is being reproduced.  You only have one
publication.  I think we have enough new formats to deal with already
without considering fax to be yet another one!
