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.
