This paper is designed to complement Richard Young's (1976) survey, which identified the four main theories of rhetorical invention (neo-classical invention, prewriting, tagmemic invention, and the dramatist invention), by reviewing textbooks under the headings of the four rhetorical inventions. A fifth category, resources in speech communication, is included because it represents a field which is helpful for the teaching of writing, and the teaching of invention in particular. This category is divided into five subclassifications: public speaking, argumentative and debate, persuasion, rhetorical theory and criticism, and communication journals. (TJ)
