DeepDyve – Search for Research

DeepDyve delivers the research engine for information-savvy consumers who want access to expert content on topics they care about. For the first time, researchers, students, technical professionals, business users, and other information consumers can access a wealth of untapped information that resides on the “Deep Web” — the vast majority of the Internet that is not indexed by traditional, consumer-based search engines. The DeepDyve research engine unlocks this in-depth, professional content and returns results that are not cluttered by opinion sites and irrelevant content.
