@Sara: You can lookup using OCLCNumber based and ISBN based URIs. Note I am not using the word ’search’. You are not searching an index for references to a number string, you asking for a description of the thing with identifier ‘ http://worldcat.org/oclc/######’. May seem a little pedantic, but it is fundamental to linked data.
As far as I am aware there is no direct access to lccn via this route. That *would* be more of a search operation: ‘return me the Thing(s), and their unique URI(s), that are sameAs the thing this identified by this’ lccn. @Cindy: All this data is openly available, as Linked Data under an Open Data Commons Attribution License <http://www.oclc.org/data/attribution.en.html>, in the way I described so you do not need an account key, or an API to access it. OCLC have APIs that also makes some of this data available via other routes. I will leave it to folks at OCLC to comment on those and any limits, or not, associated with the Linked Data. ~Richard.
