Dog Earred Pages
Ah, dog earred pages, the traceable cookies of the pre-HTML era.
When I came across this book in the bookdrop today, I saw two pieces of paper sticking out and I was hoping they were the $100 bookmarks the previous patron forgot to take out. But alas, they were just dog-earred pages. Funny thing about them was that the first one was on the chapter about "Body Odors" and the second one was on "Fertility."
Methinks, one could definitely be an inhibitor of the other.
