----------------------------Original message---------------------------- I am having problems entering the 034 field when I want the first indicator to be 0. The maps I am cataloging are old city maps and I want to put "scale indeterminable" in the 255 field as "Bibliographic Formats and Standards" (p.0:72) instructs. When I do this OCLC gives me an error message telling me I have an invalid indicator in that line. The system will accept the field if under subfield "a" I use a "z" for "Other". Does anyone have a solution to this problem? Scott
