There is no need for WP to figure this all out internally.
To my knowledge, though, the OCLC database itself is proprietary and
available only to subscribing institutions, which somewhat complicates
using it for our purposes, especially if Wikimedia's sites and their
dependencies are to remain free-software/open-content. Is there some
reasonable way around that?
