What does it take to get me to stop reading a book and put it down? there are a couple of things that will make me put a book down and not pick it up again. One is if the book gets preachy. Another is when I run into too many errors. Recently I was reading a book and I started seeing errors of fact and implied errors. The errors of fact included a description of a geographic distribution that I am very familiar with. The description, for anyone who knows the geographic region which was being described, was either very poorly written or was flat-out impossible. Soon after that description, the book implied that two places were closer than they actually are. When I got to that point in the book, I put it down and returned it to the library the next day. I can't really say how many errors make me stop with a book, but it's some combination of the number and the size of the error -- a small number of errors that seem large to me will do it, or a larger number of small errors. Either way, what does it is the idea that I can't trust the information in the book -- kind of "If this and this are wrong, how much that I don't already know is in here that's wrong? How much can I trust this book?"
