Dinosaur books for children in libraries across the country (public or school) are frequently quite old, or at least out of date. Not terribly surprising when you consider it is a topic that sits on the very edge of human knowledge, but so often attracts the interests of children. Same problem exists for space books. When I was a kid I had a few space books that referred to men "one day" landing on the moon. This was 20 years after that had actually happened.
