Greetings!  We are going to begin classifying our United Nations documents
   in LC classification. Currently they are shelved using the United
   Nations number.  Our government documents bibliographer would like
   the United Nations number preserved in a searchable field in the
   bib record.  The question is which field would be most appropriate?
   She feels the number is actually a call number and should be put in
   the 086 field.  In a quick search, I could not find an OCLC record
   putting this number in the 086 field.  The CONSER practice seems to
   be to mention this number as a "publication sales number"in a 500
   note.  This makes me think of using subfield "a" of the 037 field
   to access this number.

   How do other libraries handle access to the United Nations number?
   Any information would be greatly appreciated. Please respond
   directly to me and if there are enough responses I will summarize
   for the list.  Thanks in advance.
