CHANGES REQUIRING THE ADDITION, REVISION, OR DELETION OF A UNIFORM RESOURCE LOCATOR
Original URI no Longer Active
LC practice: When it is determined that a remote access electronic resource is no longer available at the Uniform Resource Identifier (URI) recorded in MARC field 856 $u, follow the guidelines below.
Use Internet search engine(s) to determine if the resource described in the record is now available at a different URI. If found, update the record to reflect the new URI.
If searching indicates that the resource is no longer available, create a note to reflect this fact by changing subfield $u in MARC field 856 to subfield $z and modifying the subfield to show that the resource is no longer available, indicating the last date that the resource was searched. If explicit information is received regarding the disappearance of the resource (e.g., a communication with the publisher), record this information in subfield $z as well as the date the resource ceased, and optionally reflect this date elsewhere in the record (e.g., MARC field 264 $c, MARC field 008). Suppress the record from the OPAC if the resource cannot be accessed.
Do not base the decision that a resource no longer exists on a single search. Given that servers can "go down" temporarily for various unavoidable reasons, use caution to assure that the decision is based on multiple discovery attempts on different days.
 
 
 
EXAMPLE
original record
856 40$u http://www.example.com
revised record
856 40$z Electronic address (http://www.example.com) not available when searched on [date]
 
 
 
Do not apply the procedures above in the following situations (but do notify the Policy and Standards Division):
1.
the record represents a resource from a Library of Congress domain (e.g., lcweb.loc.gov, www.loc.gov), or,
2.
another 856 field in the record indicates that LC has archived the resource, or,
3.
LC has a paid subscription to the resource.
Original URI Still Active, but Original Resource no Longer Available
LC practice: If the resource located at the URI represents a completely different resource from that described in the record (i.e., not just a new iteration of the resource), treat the existing bibliographic record as above and create a record for the new resource now at the original URI if appropriate for adding to the catalog.
