Definition | Data from foreign MARC records for which there are no corresponding MARC 21 or OCLC-MARC fields. LC and OCLC use field 886 when converting data from foreign MARC records into MARC 21 or OCLC-MARC formats when it is desirable to retain data for which there is no corresponding field or which cannot be accommodated in MARC 21 or OCLC-MARC formats for some other reason. |
1st Indicator | Type of field. The type of foreign MARC field from which the data is converted. |
| | | 0 | Leader. Information from the foreign MARC Leader | |
| | | 1 | Variable control fields (001–00z). Information from a foreign MARC variable control field. | |
| | | 2 | Variable data field (010–999 or zzz). Information from a foreign MARC variable data field. | |
2nd Indicator | Undefined. The 2nd indicator position is undefined and contains a blank (  ). |
| | | | Undefined | |
Subfields | |
| ‡a Tag of the foreign MARC field | The 3-character tag number (001–999 or zzz) from the foreign record. Subfield ‡a must be the second subfield in the field, immediately after subfield ‡2 and before subfield ‡b. If the 1st indicator value is 0 , then subfield ‡a is not present. | 886 | 2 | | ‡2 unimrur ‡a 709 ‡b1 ‡a Napalkov (Litvak), Vladimir Nikolaevich: sm. | |
| ‡b Content of the foreign MARC field | Either the 24 characters of the leader, the entire content of the foreign MARC control field (001–00z) or the entire content (indicators, subfield codes and data) of the foreign MARC data fields (010–999 or zzz). | 886 | 1 | | ‡2 intermrc ‡a 004 ‡b 10000a90001 | | [Field 004 (Corrected Fields) for INTERMARC record.] | |
| ‡c–z Foreign MARC subfield | The subfields and their content present in the original foreign MARC field. These subfields are prefaced with subfields ‡2, ‡a and ‡b. These subfields are only used when the 1st indicator value is 2. | 886 | 2 | | ‡2 ukmarc ‡a 690 ‡b 00 ‡a 00030 ‡d Great Britain ‡z 11030 ‡a butterflies ‡z 21030 ‡a life cycles | | [Field 690 (PRECIS String) for UK MARC record.] | |
| ‡2 Source of data | The MARC code of the format used as the source for the MARC record (e.g., Chinese MARC or UK MARC). See MARC Code Lists for Relators, Sources, Descriptive Conventions ( http://www.loc.gov/marc/relators/relahome.html). Subfield ‡2 is the first subfield in the field. |
| ‡0–1 Foreign MARC subfield | The subfields and their content present in the original foreign MARC field. These subfields are prefaced with subfields ‡2, ‡a and ‡b. These subfields are only used when the 1st indicator value is 2. | 886 | 2 | | ‡2 ukmarc ‡a 690 ‡b 00 ‡a 00030 ‡d Great Britain ‡z 11030 ‡a butterflies ‡z 21030 ‡a life cycles | | [Field 690 (PRECIS String) for UK MARC record.] | |
| ‡3–9 Foreign MARC subfield | The subfields and their content present in the original foreign MARC field. These subfields are prefaced with subfields ‡2, ‡a and ‡b. These subfields are only used when the 1st indicator value is 2. | 886 | 2 | | ‡2 ukmarc ‡a 690 ‡b 00 ‡a 00030 ‡d Great Britain ‡z 11030 ‡a butterflies ‡z 21030 ‡a life cycles | | [Field 690 (PRECIS String) for UK MARC record.] | |
