Anyway, I was wondering if there is a name for this linguistic phenomenon [tsuwm? nuncle?]

While we await the official word on this, WO'N, I propose to fill any vaccuum which might exist with the coinage "biblionym".

A book title which enters the language long after its leaves leave no impression is no less deserving of a name describing the phenomenon than a person whose name becomes an "eponym".

However, in a day when fame is conferred by people who have scarcely read a book out of interest, it is probably fair to judge a book by its title ... if only because that is the only thing about the publication which merits a book review.

Exhibit #1: Paris Hilton's new voyeurography: "Confessions of an Heiress. A Tongue in Chic Peek Behind the Pose".

Obviously, the best writing is on the cover.

This is an act we can all get in on!

Paris Hilton: At the Peek of my Career.

Or:

Paris Hilton: A Peep beyond the Prose.

Or:

Paris Hilton: Need I say more?

Or:

Paris Hilton: Confessions of an Heirhead

Paris Hilton adds new meaning to the the phrase "cover girl".

"Confessions of an Heiress" isn't a book. It's a cover.

"A peek behind the pose"???

The only thing we don't get to peek at "behind the pose" on the cover is her photogenic behind. No doubt that appears on the back cover.
