Field 911 was a local field used by LC for information about copies (known as "X-copies") not retained in LC collections.  Information for copies retained in LC's collection was given in field 901.

A separate 911 field was used for each X-copy.  When an X-copy has more than one custody (i.e., it was to be routed to several places), subfield $c is repeated within the field.
