If you want a quick summary of the article, here it is:
There is a positive and statistically significant relationship between children’s services in public libraries and early reading success at school. In fact, there is even the probability of even stronger statistical evidence in the future, but first we need more ambitious research on the relationship between children’s services and early reading success. In the meantime, the evidence at hand suggests that the services of children’s librarians make a real difference in children’s lives.
It is also nice to know that libraries are important to people all around the world. It might be fun to read My Librarian is a Camel: How Books are Brought to Children Around the World by Margriet Ruurs [J 027.42 RUU] with the children in your life and discuss how important libraries are to you and them. In a few short years, these children will be voters, too, so it's never too early to build support!
