The present collection is the fourth and last volume in a series titled »Dictionaries Under Discussion« (cf. Lexicographica. Series Maior 27, 70, 84) in which all the participating scholars have been concerned to provide new impulses for lexicographic research in its four major fields: user research, systematic lexicographic research, historical dictionary research, and dictionary criticism. Like the last volume, this one containing papers held at the Heidelberg Lexicographic Colloquium in the course of the winter semester 1997/98 and summer semester 1998, charts out the potential research paths for lexicography on its way into the new millennium.
