This "encyclopedia" contains amatuerishly written articles which are too brief. Subjects, that are covered, lack detail and depth. Most disappointing are the illustrations, photos, maps, etc., they are too small and offer limited information.
World Book is definitely a poor example for an encyclopedia and certainly not worth the $20. A price of $3.99 is about all this encyclopedia is worth.
Save your money and use some of the far superior, free excellent sites on the internet.
