How and Why Wonder Books were a series of illustrated American books published in the 1960s and 1970s that was designed to teach science and history to children and young teenagers. The series began in 1960, and was edited under the supervision of Dr. Paul E. Blackwood of the Office of Education at the U.S. Department of Health, Education and Welfare. The series was published by Wonder Books, Inc., a division of Grosset & Dunlap.
There were 74 unique titles in the series, each one starting with the phrase The How and Why Wonder Book of… as a key component of the book’s name. All 74 volumes were published in a softcover format, with pages measuring 8½ × 11 inches (21.6 × 27.9 cm) in size. A number of the titles were also produced in hardcover versions, too; these being referred to as either the “Trade Editions” or the “Library Editions.” Each How and Why Wonder Book uniformly contained a total of 48 pages, with the only exception being The Environment and You, which contained 64 pages.
The softcover books were numbered consecutively in series starting at 5001 (with the only exception being the final book in the series entitled Fossils). The hardcover versions were numbered differently from the softcover issues.
