Note: The examples below are not intended to be an exhaustive list of all possible cases of compliance.
The table below describes some common examples of restrictions on headings based on the codes in the 008 field in the Library of Congress authority record.
LC MARC coding that initiates compliance |
Field and heading entered in bibliographic record | Result in bibliographic record (field conversion supplies authority control) |
---|---|---|
008/16 = b | 830 _0 Today (London, England) | 730 _0 Heading cannot be used as a series. |

Field tags (in some cases) Miscoded subfields |
Data entry errors, such as topics |
When adding authority control to a geographic subfield (‡z), the system uses the 781 field, if available, then the 151 field. Because not all authority records currently contain 781 field, in some cases, a geographic subfield cannot be controlled in its correct form.
