Bibliographic record

The Bibliographic record describes the item being catalogued. The fields explained here are used at Wellcome (or have been) and include specific local uses.

• It is recognised that the cataloguer may not have information to populate every field.

• Where fields can be repeated the field title is followed by (R). Non-repeatable fields are marked with (NR).

• Field examples are formatted to allow the content to be copied and pasted straight into Sierra.

Full details for each MARC field and subfield can be found on the OCLC Bibliographic Formats and Standards pages, which should be considered an additional cataloguing resource.

Follow International Standard Bibliographic Description (ISBD) punctuation rules.

You can also view a MARC crosswalk showing any local uses of MARC fields.
