The following table describes other errors, how they can be prevented, and whether they can be addressed by preprocessing routines in bibliographic collections. For more information about how OCLC's Duplicate Detection and Resolution (DDR) software deals with bibliographic records, see Cataloging defensively.
This table provides examples of frequently found errors and is not exhaustive.
|Type of common error||Description of error||Prevention||Preprocessing routine available?|
|Country codes (008/15-17)||
|Language codes (008/35-37)||Language codes (008/35-37) have uppercase alphabetical characters.||
|040 $b||OCLC encourages its members to include the language of cataloging (040 $b) in records. If not included, the language of cataloging is English by default. Therefore, the lack of a code in a record with cataloging data in a non-English language misrepresents the cataloging.||
||Most often, no. Preprocessing cannot supply a language code in 040 $b unless it applies to all records.|
|040 $e||Cataloging description MARC code was noted in the 040 $e||
|6xx||Subject headings are coded as local with 2nd indicator of 4 or with 2nd indicator of 7, and the source code is noted in $2.||
