I agree that you have to look at more than the ranking number to make a decision. When I use K1000 to check on a book, I look for single letters as well as broken words. And of course a little spot checking.

I suppose you could do a ranked spelling and see what the percentage is, but that could be misleading if there are a lot of proper names and special words, as SF and Fantasy have. If a book is of poor quality, it won't take long to find out just reading here and there around the book.

I don't want to donate a book just to find out that I should have bso-ed it. We all know that some books were called excellent when they aren't by current standards. Is there a quick way to figure out if a book needs bso-ing. Thanks.
