Medical information this old is a slam dunk for weeding, especially if we are talking about material published over 20 years ago! Teen and youth nonfiction titles, in my opinion, actually need more vigilant weeding. Even “slightly” out of date can make libraries look useless in the eyes of young people. Remember your audience and clean up the teen and youth nonfiction. They deserve the best we can offer!
Stepping off my soapbox now!
PS in the meantime take a look at these “helpful” pictures featured in this book! These are some of the best shots. This particular book was low on content and low on meaningful pictures/illustrations/charts. Evidently the best treatment for Alzheimer’s Disease is a visit from the clergy and a computer lesson.
