Many thanks for everybody's help on this one. I did a Yahoo! search for UNIPUB, which one respondent gave as the US distributor of NRPB literature. They gave the following phone/fax nos:(301)459-7666, tollfree USA (800)274-4888 and Canada (800)233-0504, fax (301)459-0056. They also appended a note reading:"Some people have reported difficulties in contacting Unipub." chris alston ccja@aol.com
