I'm not sure about your specific book, but I know that there are books that are listed by the author's first initial and sometimes their middle initial.  Seems to be an "input" error.  But you can find many "lost" books that way.

There is a giant data base project going on to up-date and correct information by Author, here at PBS. If you would like to help, click on Approve Book Authors at the bottom of the page, in the blue ink under the ^Back to Top^ link. Since the data base is purchased from an outside source, there are errors in it. But we can clean up the data base and make searching easier for everyone.
