4xx Fields

4xx Introduction

4xx fields

Use field 490 for series statements transcribed from the item. Also use field 490 for name/title series statements found in retrospective cataloging copy.

Obsolete 4xx fields

Fields 400, 410, 411, and 440 are obsolete. OCLC has run a database scan to convert them to field 490 with corresponding series access points in 8xx fields. Records containing these obsolete 4xx fields fail validation. You may find these fields in local systems in records used prior to this change.

Relationship to 8xx fields

Use 8xx fields for series access points. Use fields 800, 810, or 811 for series access points in name/title form and field 830 for series access points in title form.
