Having indexed much of the "surface" Web, search engines are now using
various approaches to index the "deep" Web. At the same time,
institutional repositories and digital libraries are adopting the Open
Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) to expose
their holdings. The authors harvested nearly 10 million records from
OAI-PMH repositories. From these records, they extracted 3.3 million
unique resource URLs and then conducted searches on samples from this
collection to determine how much of the OAI-PMH corpus the three major
search engines have indexed.
