The first version of Noesis: Philosophical Research On-line appeared on the Internet in 1998. It was born out of insights acquired while implementing two earlier search engines, Argos: Limited Area Search of the Ancient and Medieval Internet (1996) and Hippias: Limited Area Search of Philosophy on the Internet (1997). These projects were based on the notion that if users could search a carefully selected sub-section of the Internet, search engines could implement a kind of peer review, separating the wheat from the chaff and harnessing the power of the Internet for scholarly purposes. Both Argos and Hippias limited their scope by searching a set of "associate sites" and everything to which they linked, in effect passing editorial control over their search spaces to the editors of the various associate sites. The current version of Noesis runs on the backbone of Google through an interface provided as part of the Google Co-op.
