This is a state-of-the-art volume on lexicography at the beginning of the 21st century. It also offers proposals for future theoretical and practical work. The contributions, inspired by the ground-breaking work of Henning Bergenholtz, address topics such as dictionary functions; dictionary users; access routes; dictionary structures; dictionary reviewing; subject-field classifications; data retrieval; corpus lexicography; and collocations and phraseology. The contributors, all highly regarded international scholars in the field of lexicography, show how the theory of lexicographical functions can extend the forefront of the discipline by focusing on dictionary functions and how these meet the needs of users in various types of user situations. Thereby echoing Bergenholtz’s idea that a dictionary is a tool that can help users solve problems encountered in communicative, cognitive and operative situations.
