Enter LCCNs in records (field 010)

Discover how to enter LCCNs in records (field 010) in Connexion client.

Overview

When you add or correct an LCCN:

  • Enter all non-blank characters.
  • After you reformat or take an action on the record, Connexion displays the LCCN with no hyphen, 1-3 leading blanks in unoccupied prefix positions, 1-5 leading zeros in unoccupied number positions, and (pre-2001 LCCNs only) a trailing blank in position 12.

    Displaying the LCCN without the hyphen is consistent with the way LCCNs display in newly published materials.
  • In most cases, the system can supply blank spaces in the prefix and/or a final blank as required to format a valid LCCN; you need not enter blanks.
  • If you enter the LCCN with a hyphen, you need not enter leading zeros in the serial number; the system can supply them. However, if you enter the LCCN without a hyphen, you must include leading zeros.
  • Validation errors on field 010 often result from too many characters in any portion of the LCCN, embedded blanks in any portion, missing letters or numbers, or (if you omit the hyphen) missing leading zeros in the serial number.

The following tables provide details on required formatting for both pre-2001 LCCNs (2-digit year) and current LCCNs (4-digit year). In the tables, note that each underline character represents a space.
