856: Electronic Location and Access

Introduction | Copy Cataloging Instructions | Reference Information and Examples




Field 856 is most commonly used for links from bibliographic records to internet resources.  The field may also contain information about access to the resource, as well as information about the content being linked to. 


Use field 856 in a bibliographic record for a resource when that resource or a subset of it is available electronically. In addition, use field 856 to locate and access an electronic version of a non-electronic resource described in the bibliographic record or a related electronic resource.


 In bibliographic records for books, related electronic resources may be table of contents information, summaries of a book, a website devoted to the exhibition described in the book, or the complete text of the book in electronic form, etc.


Copy Cataloging Instructions


1st Indicator: Access method

         Verify that the 1st indicator is 4.  If it is not, take the material to the electronic resources cataloger.

2nd Indicator: Relationship

         Accept the second indicator on incoming copy.



|u: Uniform Resource Identifier


      If the link is to Library of Congress-hosted content (recognizable by starting with http://www.loc.gov/,) accept the link without checking it.


    For non-LC links:


1. Verify the accuracy of the link.  In the Voyager Cataloging Client, this can be done by typing CTRL + K and clicking on the link in the pop-up window. Verify that the linked website matches the content of the book.  If it does not, or if the link does not work, consult the electronic resources cataloger.


2. Check the materials specified (|3) or public note (|z) fields to see if they indicate the type of material that is available.  Verify that what is in the note matches the content being linked to (i.e., if it says |3 Table of Contents, make sure your link goes to a table of contents).  If it does not, or if you are not sure, take the material to the electronic resources cataloger.


3. Verify that the content available from the link is accessible without a password or subscription.  If a password or subscription is required, delete the 856 field.  If you are unsure about whether a subscription is required, consult the electronic resources cataloger.
