856 Electronic Location and Access (R) (Variable Data Field)
Field 856 contains the information required to locate an electronic item. The information identifies the electronic location containing the item or from which it is available. It also contains information needed to retrieve the item by the access method identified by the first indicator position. The information contained in this field is sufficient to allow for the display of an electronic resource.
Field 856 is repeated when the location data elements vary (subfields $a, $b, $d) and when more than one access method may be used. It is also repeated whenever the electronic filename varies (subfield $f), except when a single intellectual item is divided into different parts for online storage or retrieval.
In USMARC classification records, this field may be used to link to an electronic resource intended to supplement the classification scheme, e.g. an image of a map.
Field 856 is repeatable.
