three books in a series is a trilogy, what is the term for two books in a series? I know, for instance, that a four book series is called a tetrology. What would five, six, etc. books in a series be termed?

How about pentalogy (5), hexalogy (6) and heptalogy (7)? I suppose you could even create a dialogy for 2.
