Encyclopedia of Science (10 Vol. Set)

Entries vary in length from 250 to 2,500 words. Longer articles are divided by subheadings, adding to clarity. As is common format for UXL publications, extensive cross-referencing directs users to related articles, and sidebars define "Words to Know." Most of the photographs and technical diagrams are in color, a definite improvement over the previous edition's all black-and-white illustrations.
