Submitter: Books that prognosticate are in a category of their own as far as weeding is concerned. How ridiculous this claim now looks. Note it was 2001 when this author claimed China would collapse in five to ten years. The problem is that these books are scattered throughout the collection, without a unifying subject heading or even a recurring title keyword to help you find them. The only solution is frequent, thorough weeding of every section. From the Mayan calendar in 001.9 to this gem in 951, I’ve had a busy week weeding old predictions that failed to come true.
Holly: These are fun to look at after the fact, but for a truly relevant collection, feel free to weed them when the prediction fails. In many cases, you can weed it even if the prediction holds true. Unless Mr. Chang’s work is still popular or important in your library, most of us can let go of this book.
