General code structure

The swissbibMARC format code consists of three values that are stored in three pica-plus-subfields and are concatenated during export in one swissbibMARC subfield.

The swissbibMARC-format-code is used:

  • as format filter code for search and retrieval over the swissbib search interface (facetting and advanced search)
  • to generate the format icons
  • to generate the format label

For IDSMARC data the codes can be used in connection to the format strings in swissbibMARC-field 908. For MARC21-data they represent the only direct access point.

The field structure looks like this:


#008@ $a <primary code> $b <secondary code> $c <tertiary code>


#898 \\ $a <primary code><secondary code><tertiary code>

primary code

The main code is based on MARC-Leader position 6 and if necessary position 7. The primary code consists of two uppercase alphabetic values and two digits. The following codes are used:

CL05 Fallback code, when no format has been identified. Should be corrected as soon as it is discovered.

secondary code

The secondary code is based either on the combination of LDR position 6/7 and field 906 for IDSMARC or on the combination of LDR position 6/7 and values of 007 and 008 for MARC21. The secondary code consists of two digits. If there is no special code assigned the base value is "00". The following values are possible (xx stands for different tertiary values):

tertiary code

The tertiary code is either based on 907 for IDSMARC or on 007/008 for MARC21. The tertiary code consists of two digits. If there is no special code assigned the base value is "00". The following codes are used:

Code Description

About the field 898

During the deduplication of the same records from the various library networks, one field 898 is created. When contradictory data exist in the record that are merged, more than one field 898 can be generated. Therefore a document can have various formats. This is useful for the search interface: the document can be found through various facets.

However, the LDR field contains only one data format.
