Creative Bookshelf

• In several stories, a secret area is hidden behind a bookcase built into the wall. The entrance is typically opened when a particular book on the shelf is pulled off or uses a switch in a statue, usually under the head. One particularly humorous example is found in the film Young Frankenstein, when Doctor Frankenstein's laboratory is opened via a bookcase triggered by a candle.
• H. C. Bunner wrote a comic poem "Shake, Mulleary and Go-ethe" "I have a bookcase which is what / Many much better men have not / There are no books inside, for books / I am afraid might spoil its looks, etc."
