This symposium paper discusses the role of dictionaries in the process of writing and the effects of computerization. The authors include examples of several different hypothetical lexical searches and their outcomes, based on a writer's needs, and argue that these relationships differ from what is to be found in lexicons. A key point is that writers often want to break habits of thought, predigested thinking and prejudice, in which case dictionaries will not directly serve their writing requirements.
