  Alphabetic prefix
    Prefixes are carried in a MARC record as lowercase alphabetic characters and serve to differentiate
      between different series of LC control numbers. Prefixes are left justified and unused positions
      contain blanks. If no prefix is present, the prefix portion contains blanks.
