Cataloguing Source Codes

One of the requirements for digital catalogue records is the ability to identify which organisation created the record and who has modified or corrected it.

In MARC21 format, the cataloguing source code is written in field 040.

Read more about filling in field 040:

• ELNET Consortium’s cataloging instructions for book or other information material (in Estonian)
• MARC21 manual from the Library of Congress

• Creating the code

  The registrar who is the National Library of Estonia should be notified of every code issued.

  • It is mandatory to add the code of the library that created the original record, modified the content data or corrected the existing record.

  • The codes must be unique. Therefore, when providing codes, it is advisable to keep in mind other potential organisations in the area that might also want a code.

  • Research and special libraries create their own codes

  • Central county libraries create the codes for public and school libraries

• Issued codes
  • Public and school Libraries
