While in Cody's Book Store today, a man set off the
anti-shoplifting alarm when he (accidently?) walked out with
2 books under his arm.  The salesclerk told me that they used
magnetic strips in some of the books.  Interestingly, the books
that set it off were paperbacks (one was a large paperback).
Are these strips put in when the book is made?  Are dectectors
really sensitive enough to detect magnetic strips?  If so, will
a magnet, carried in your pocket, set it off?
