Title: An excellent reference source for general science
Review: Although there are some errors, this is the best general reference source I have encountered. Considering its breath of information, its accesibility, and its cost, this is an excellent reference for high schools and high school and college students. The organization of the book invites people to look up a specific piece of information. The book includes sections on constants, units, biology, chemistry, geology, physics and mathematics. The book includes obscure as well as often used information. This would be an excellent book to give to a person who would need or be interested in some of the tools of science.
