A couple of folks asked me about article level metadata in worldcat.org as in, for example:
Details are available on the OCLC website:
OCLC has added article-level citation records to WorldCat.org search results from four FirstSearch base package databases: GPO, ArticleFirst, Medline and ERIC. [Article-level citation records added to WorldCat.org [OCLC]]
Worldcat.org offers other library services if it recognizes an incoming IP address. So, for example, here is what I see. I have links through to a resolver and catalog at the OCLC Library which show up as links under the entry. It will link through to fulfilment options where it knows about them; here it knows that my library subscribes to an appropriate fulltext resource so I can go through.
