Some instances of an understudied genre, predominantly satirical:
Bierce, The Devil’s Dictionary
Flaubert, Dictionary of Received Ideas
Fowler, Dictionary of Modern English Usage [which I include under the banner of satirical for such entries as “genteelism”]
Heifetz, Mrs. Byrne’s Dictionary
Slonimsky, Lexicon of Musical Invective
Voltaire, Philosophical Dictionary
How far can the dictionary form depart from the norm? Can there be a dictionary (or encyclopedia?) of—say, jokes? What else? Another lexicographic genre is that of the collection of keywords (not quite a straightforward glossary or scholarly lexicon)—for a culture, for a theme, for a discipline. Some examples:
Barthes, A Lover’s Discourse
Jay, Cultural Semantics: Keywords of Our Time
Lewis, Studies in Words
Williams, Keywords: A Vocabulary of Culture and Society
