Query: Informative But Slow And Not Entertaining

Naturally, one wouldn't expect a book on the history of the bar-code to be particularly entertaining. This doesn't even manage to fulfill my lowest expectations. Still, the content is valuable for an understanding of how standards come about, and also some tidbits on the future applications of barcodes. I read this for a class I took on information technology and policy, and there are a host of far more interesting books on similar subjects that I would recommend before this. I suppose this is supposed to be an exclusively academic read, so perhaps I'm being too harsh. Then again, the content and writing was too simple and accessible to be very esoteric--so maybe I'm not. Whatever. Regardless, don't buy this book unless you're wildly interested in the history of the bar code. If you are, see a shrink too.
