I don't really see how they can justify the title when they admit right in the book that there are at least two Harold Shea stories that didn't get included (those extra stories can apparently only be found in The Complete Compleat Enchanter)
A group of psychologists figure out that by mathematically expressing the assumptions of another world (such as one where magic works) and holding the equations firmly in mind, a person can transfer himself to that other world. This leads to stories set in Norse myth, Spencer's Faerie Queen, and Ariosto's Orlando Furiosio (with a brief stop in Coleridge's Xanadu).
The writing has a strong pulp flavor, but the underlying rules of magic are fairly rigorously worked out. Combines college-level English literature with early high-school level emotional maturity. Like too much fantasy and sf, especially the early stuff, it seems aimed at arrested (or to be fair, actual) adolescents.

Back before I changed jobs and started working insane hours, I used to keep a book journal. Because I haven't had the time to generate any new reviews, I'll post a few of my older ones here.
