The "Eyewitness Companions" are a series of wonderfully designed guide-books on a variety of topics, from Religions to World History to Wines to Baseball to countless others. Each is loaded with beautiful photographs and illustrations. The books are compact in size, making them easy to carry, but they are also hefty in content, providing hours of reading pleasure.
My home library collection already has a bunch of them: Art by Robert Cumming, Mythology by Philip Wilkinson and Neil Philip, Astrology by Julia and Derek Parker, and my favorite Film by Ronald Bergen.
There are "Eyewitness Companions" about Golf, Whiskey, Fishing, Philosophy, Weather, Architecture, Opera, and Beer.
DK Publishing produces some fine, large hardcover illustrated books, covering the history of various comic book titles, the broad spectrum of science and nature, and beyond. But the "Eyewitness Companions" are a delightful gift for anyone who has a passion for a specific topic or for anyone who just wants a series of great books.
