RunningReader I used the WorldBook to search "cats" in both student and library editions. It was interesting to see how the material was adjusted for the age groups. Each looked much the same but more info was added and more pictures.
I spent some time in World Book Advanced looking at Lithuania, the country of my ancestors. I liked the pictures, maps and the related information provided. It was hard not to spend a lot of time going from interest to interest. Citation information is a big plus for any student.
The Foreign Language Visual and the encyclopedia are a great addition to any library, since most of us have some patrons who speak Spanish. The fact that the article could be read in either English or Spanish for the viewer is a big value added resource.
The tutorials in all of the sections were helpful although I imagine, like me, most students would just jump in and start looking around on their own.
