As an example, the URIs http://www.worldcat.org/oclc/829279 and http://lccn.loc.gov/74155758 each lead to information about John Hayes' Late Roman Pottery published in 1972.
Which one of these is preferable as the long-term description of this volume? Worldcat or LOC. The use-case is a digital publication with bibliography that ideally includes a link to one or the other or both for all printed volumes or other appropriate entities.
Perhaps a discussion will ensue in the comments but here are some quick issues:
- There are multiple URIs for that one volume in Worldcat. http://www.worldcat.org/oclc/462730938 gets you to the Danish Union Catalog.
- There are still concerns about the licensing of Worldcat data.
- The LOC record is to a physical volume in a single national library and may not be intended as a description of the abstract concept (e.g. a FRBR Work). I don't know that Worldcat URIs solve this problem but they have the implication of a higher level of abstraction.
