This book, like many others, is a collection of works the author has written. In other collections, he has tried to give as much as possible about a given topic. "The Best of Jonathan's Corner," available via searching on Amazon, has a collection of favorite works that totals to about 700 pages. (The author is somewhat prolific.) This collection is meant to be the opposite of that encyclopedia approach. It's meant to give a little taste of what, exactly, some people have found interesting. But it is meant not to be a long and daunting read, only short and inviting. A sort of elevator pitch, as far as books go. If you like it, you are welcome to explore more works by the same author; they can be found by searching Amazon for "The Collected Works of C.J.S. Hayward." The author is intentionally not trying to convince you of what so-and-so said about one of works, or what his credentials are, but merely give a tiny slice of carefully chosen works work. If you read these short works and want more, then you will know this without being told. It is hoped that you will like them but that decision remains with you.
