Lancaster is followed by nine papers: (1) "Linking the Unlinkable" (Michael Gorman); (2) "Aristotle Meets Plato in the Library Catalog: Part 1" (Ward Shaw); (3) "Aristotle Meets Plato in the Library Catalog: Part 2" (Ken Dowlin); (4) "Toward a Definition of User Friendliness: A Psychological Perspective" (Christine L.
