Hi, everyone. I am working on a natural weight loss cure book. On page 157, there is a plastic rectangle approximate one inch long and approximately a half-inch wide stuck to the book permanently. The weird thing is that the scanner apparently recognized everything on the page; the plastic strip didn't interfere with recognition as far as I can proofread. Has anyone else seen these strips in books before? Is it one of those security tags that stores sometimes forget to remove from products? I am curious. Linda Adams
