MarcEdit’s linked data tool is somewhat experimental, but it allows users to automatically generate links to resolve access points from the LC or OCLC VIAF authority records. Using this tool, it is possible to append linked data to 1XX, 6XX, and 7XX fields. What follows is a brief demonstration of this functionality and a results comparison based on different options selected.
Click Link Identifiers. This will take you to the linked data menu page.
Regardless of whether or not you select the Library of Congress or OCLC VIAF (which relies on the LC NACO by default), the first 650 subject field is given linked data, but AutoDetect Subject IDs must be selected in order to generate the WorldCat fast ID URLs for the rest of the subjects. As one would expect, the authors name has been registered in either the Library of Congress or VIAF. Because the OCLC relies on LC (NACO), there is a URL created linking to the authority record for the geographic heading but no other subject headings.
