Newer generations of library catalog systems, typically called discovery systems (or a discovery layer), are distinguished from earlier OPACs by their use of more sophisticated search technologies, including relevancy ranking and faceted search, as well as features aimed at greater user interaction and participation with the system, including tagging and reviews.
In a small percentage of libraries, [29] the local catalog is also run by OCLC using an integrated library system called WorldCat Discovery and WorldShare Management Services. [ 30 ] Library contributions to WorldCat are made via the Connexion computer program, [ 31 ] which was introduced in 2001; its predecessor, OCLC Passport, was phased out ...
Catalog resolvers are available for various programming languages. The following example shows how, in Java, a SAX parser may be created to parse some input source in which the org.apache.xml.resolver.tools.CatalogResolver is used to resolve external entities to locally cached instances.
