It's possible:
* The name is misspelled. Perhaps a slight variation exists.
* The author is less known. They may have written in a niche genre or under a different pen name.
* They are a newer author. Their work may not be widely recognized yet.
To help me find the right author, could you provide more information? For example:
* What kind of books do you think they write? (genre, style, subject matter)
* Do you know any other details about them? (nationality, era, etc.)
* Do you have any specific titles or excerpts in mind?
With more information, I can search more effectively and help you find the right Lionel Corbett!
