I found the World Book site to be a wonderful resource. The site was easy to navigate and to find what I was looking for. I liked how the information started out simple for the younger kids, and then got more advanced in the student version. The information on how to cite the articles is a great resource also. When researching a country in the Advanced version it was nice to have the sidebars so you could go directly to the information you wanted rather than having to scroll through the entire article to find what you are looking for. Plus the fact you can have audio for pronunciation of words, and can actually have the text translated into a foreign language is terrific. With our growing population of people moving into our country this is a very helpful resource to direct people to.
