Resource discovery

Approaches to Internet resource discovery:



• Robot-based global indexes, e.g. Alta Vista, Lycos, etc.
• Subject gateways - e.g. ROADS-based services
• Library catalogues, e.g. using USMARC 856 field - InterCat project (OCLC), BIBLINK
• Need for “core” metadata for simple resource discovery and interoperability - Dublin Core initiative
