[A Book of Venus for You] gives an excellent, extremely up-to-date survey of what is known about Venus. Every recent discovery about the planet by United States and Russian space probes and United States radar observations is included. The explanations are very clear and concise, and the book is quite readable. There is one quibble, however. Dr. Branley says a "day" on Venus is 247 days long, while a year is 225. "Day" is an ambiguous word in astronomy but most people would assume the author meant time from sunrise to sunrise. On Venus a Solar Day is only about 120 days long, while it is the "sidereal day" which is about 247 days long. Other than this little inaccuracy the book is flawless. (pp. 5-6)
