They are certainly cheap and easy to use. But the data collected is usually incomplete, often difficult to read, and impossible to analyze. And perhaps more importantly, confidential information about who has recently visited your facility is out in the open and readily available to anyone who wants to flip through the book''s pages. These drawbacks may have been acceptable up years ago, but post 9/11, tighter security is now a necessity.
