by Michael Kelley, editor-in-chief of Library Journal, on October 11, 2011 "...a recent report called "Paths of Discovery" by Andrew Asher of the Bertrand Library at Bucknell University (and others) notes that discovery systems exert "a form of epistemological power by virtue of their relevance ranking algorithms." ... "The critical question for librarians is therefore how to participate (or not to participate) in this process [the subject's process of discovery ?] and what level of this epistemological power to exercise," the report says" "The discussions revolve around whether the ILS should serve as the front end (bringing in the discovery results) or whether the discovery service should be the front end (interacting with traditional ILS functionalities, like holds lists)."
