This is a perfect supplement to Mary Doyle Springer's pioneering Forms of the Modern Novella. Richter, who acknowledges Springer's work, provides a somewhat clearer and simpler framework for analyzing novellas, founded on Springer's basic structure.
He divides novellas into two basic forms:
I. Mimetic II. Didactic
Mimetic corresponds to Springer's Action, in which the plot reveals a character or shows the character in the process of learning. It focuses on the world within the fiction.
Didactic corresponds to Springer's Apologue and Satire, where the focus is on the world outside the fiction, either teaching the reader something about it (Apologue), or else mocking an aspect of it (Satire).
The bulk of the book consists of ten novellas which the reader can profitably analyze in terms of the provided framework:
Nikolai Gogol The Overcoat Herman Melville Billy Budd, Sailor Henry James The Aspern Papers Kate Chopin The Awakening Joseph Conrad Heart of Darkness James Joyce The Dead Franz Kafka The Metamorphosis D. H. Lawrence St. Mawr Katherine Anne Porter Pale Horse, Pale Rider Thomas Pynchon The Crying of Lot 49
The Teacher's Edition of the book contains substantial critical analyses of each novella; these are definitely illuminating and highly recommended.
