About 856 Field settings
WorldCat records include 856 fields and various URLs that are not accessible to your institution. For records from knowledge base collections, Collection Manger removes the URLs from WorldCat records and adds your library-specific links.
Titles are often available through more than one provider. If you have a title in multiple knowledge base collections, Collection Manager will deliver a single record for the knowledge base title and the record will have multiple URLs.
By default, your library will receive updated records when titles are available through new providers and the relevant URLs will be added in those records. Likewise, your library will receive updated records when providers no longer offer titles and the relevant URLs will be removed in those records.
When Collection Manager processes records for your library, it will modify the 856 fields for your records according to your customizations.
To customize 856 fields:
- Vaya a Configuración de la institución > Registros MARC > Personalizar registros.
- Complete one or both of the sections with 856 field settings:
- Complete the Knowledge Base Collection 856 Field settings for records from knowledge base collections in Collection Manager
- Complete the WorldCat 856 Field settings for records from query collections, cataloging partner collections, and for update records for your WorldCat holdings
For complete instructions, see MARC Records, Knowledge Base Collection 856 Field.
Si su ILS requiere un registro MARC independiente con una única URL para cada instancia de un título electrónico, puede seleccionar la configuración a nivel de colección para que los registros de una colección se entreguen en un archivo independiente y seleccionar una configuración para aislar la salida del archivo de otra actividad de la colección. Para obtener más información, consulte la configuración de la salida del archivo de entrega a nivel de colección de la base de conocimientos.
