I just wanted to share with everybody a little bit about Usborne childrens books. We own quite a few, and they're really great. Last year, my son's class was doing a research project on medical advances during the last century. He took the Usborne Book of World History Dates to class with him to help with his research. The teacher loved it so much, she bought several copies to keep in her classroom for future projects! They have books for all age ranges and interests. They're also a great supplement for those who are homeschooling.
