Wade Wright Biography - Information About the Author
Wade Wright, born 1933 re British Library, is a pseudonym of John Wright.
As far as I'm aware none of the books above were published in America, unusually though they do appear to have been translated into German and published in paperback format there!.
Collectors will face the usual problem with this publisher, that being small print runs most of which went to public libraries.
Nice copies in dustwrappers can be found though with prices not too prohibitive.
Readers are ill-served I'm afraid as I don't believe they were issued in paperback or reprinted so first editions only . . .
There does appear to be a more modern author using the name Wade Wright but writing very much different content
