Yes, I've seen that expression somewhere and I don't like it.
Particularly because what has made Mr Adams so famous is
The Hithchiker's Guide to the Galaxy, which is a radio-play that was later turned into books (plus a computer game and a TV series). And lately, his Starship Titanic, Which is a computer game, and which is also later written into a novel (By Terry Jones if I rememeber correctly)

Mr. Adams has also written other books, but not as famous.

Yours humbly
