Note about previous coding practices of audio visual materials
- Previous practice mandated placement of the 007 for audio/visual materials in the holdings record instead of in the bibliographic record, even when the format described in the bibliographic record matches the format of the materials in the holdings record. When updating one of these legacy records, please remove the 007 from the holdings, since conflicts between the holdings and bibliographic 007 might cause a duplicate in the OCLC Data Sync process.
