MARC documentation offers the pattern +-ddd.dddddd as one of the decimal degree formats we use in the 034 field. There are 6 digits after the decimal point. I have coordinate data with 7 digits after the decimal. Is the length of the pattern numbering capped at "3-decimal-6"? The MARC examples mimic the pattern. http://www.loc.gov/marc/authority/ad034.html -- Mark K.
