what??

I love out local library, especially their online resources for browsing books and placing holds. I was doing a search this morning to see what new knitting books they have gotten it (they have a pretty extensive collection), and this one popped up:

Nuclear Jihadist [electronic resource]:
the true story of the man who sold the world's most dangerous secrets ... and how we could have stopped him
by Frantz, Douglas.

Okay, I have nothing against non-fiction books I read a fair number of them. Bu I'm trying to figure out how this book got in the list using the keyword "KNITTING"...
