I like the idea, but in the long term, I just don't know how useful
this will be. By and large, these identifiers are designed for dead
tree resources. Although they are sometimes assigned to electronic
resources, I find it hard to believe that the containers these
identifiers are associated with will contain more than a tiny
proportion of the information users want/need. The book structure just
doesn't make nearly as much sense in an online environment.

Not sure I understand the use case (i.e. the value of retrieving
One thing to keep in mind is that although the numbering schemes are
independent, they can be thought of as hierarchical. Anything that has
an lccn number should already have an isbn because of the standards lc
catalogs to. And they put their holdings in OCLC, so all numbers that
have an oclc number should contain these other identifiers. Items with
oclc numbers that were not cataloged by lc should also have isbns.
When such conditions are not met, it is a sign of a record containing
