CiteProc is a comprehensive solution for bibliographic and citation formatting. It consists of an easy-to-use XML citation style language (CSL), and the XSLT code to format documents based on them. In essence, it is designed to serve as an XML-based analog to BibTeX, but with dramatic improvements in ease-of-use, metadata flexibility, and international support.
CiteProc reads the source document for citation references and collects the corresponding records from an external bibliographic data store, and then formats the bibliography and citations according to specifications in the CSL file.

WorldCat Link Manager is an OpenURL linking and listing service that allows users to link from an article citation in WorldCat to the full-text version of the article. WorldCat Link Manager "puts it all together" for libraries that don’t need the hassles of running their own link-server operation.
