SUBFIELDS

950a Access point

Use this subfield to enter the complete access point and all punctuation marks between individual pieces of data.

9502 System code

This code denotes the subject system that the access point belongs to.

9503 Record number

This subfield contains the identification number of an authority record from a foreign list.

9505 Relationship control

This code denotes the relationship between the related access point in field 950 and the authorized access point in field 2XX.

NOTES ON FIELD CONTENTS

The field 950 is only used in records in the General List of Subject Headings (SGC) authority database. The field is filled out when an authority record should be linked via a 5XX field to an authority record for a related term, but that is not possible because the latter record does not yet exist in the base. Therefore, enter the data on the related term to field 950 instead of filling out the 5XX field for the related term.

If possible, use the corresponding access point from the Library of Congress Subject Headings (LCSH) list or from the Répertoire d'autorité-matière encyclopédique et alphabétique unifié (RAMEAU) list as the link. Enter the access point to subfield a, the LCSH or RAMEAU system code to subfield 2, and the LCSH or RAMEAU record identification number to subfield 3. If neither LCSH nor RAMEAU contain the corresponding record for the related term, enter the access point written in Slovenian and created according to SGC rules to subfield 2, and leave subfield 3 empty.
