Automatic compliance with Library of Congress authority records
- When you control headings in bibliographic records using Connexion, the system enforces compliance with Library of Congress (LC) standards and practices.
- Compliance is triggered by the particular LC authority record being used to supply authority control, not the field in the bibliographic record to which you apply authority control.
- If you add headings but do not control them, the system does not enforce compliance with Library of Congress practice.
Note: The examples below are not intended to be an exhaustive list of all possible cases of compliance.
Restrictions on headings
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.
|008/14 = b||100 1_ Petitjean de la Rosiaere, Jean Marie Henriette, ‡d 1875-1947||Heading retained as entered, but not authority controlled.|
|610 20 ‡a Ohio||651 _0 Ohio|
|008-09 = b||650 _0 Area||Heading retained as entered, but not authority- controlled
Results set when available.
|008/15 = b||651 _0 Ceylon|
|008/14 = b||700 3_ Walz family||600 30
Heading cannot be used as a name. Heading only valid as a subject.
|Error corrected||Error not corrected|
|Field tags (in some cases)
|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.
