How Should the Identifier be Filled in?

 

Guideline Example
  • Enter the identifier exactly as it is found in the item or record
 

M1500.G68 A4

  • Whenever possible, include at least one relevant identifier
  • Include additional identifiers if they aid information-gathering
b2695683

50684665

Z232.A56 J67 1853z
  • For Local Control Numbers, include the Institution code followed by an underscore ( _ ) before the number
  • Local practice (within UNT Digital Projects) is to change some punctuation of Local Control Numbers when they are used as filenames during scanning (for example, '.' becomes '-'); generally, the identifier is entered using file-name punctuation rather than the original punctuation
