This non-fiction book about inventions is beautiful and fascinating.  Full of dramatic, detailed and colorful illustrations, this book vividly documents great inventions over the ages.  Early developments such as the wheel, sail, clock, and windmill are covered up to more current innovations such as bionics and the internet.  There is a glossary and index in the back and a table of contents in the front.  Our school library serves K – 8th grade and we have 8 other books from this series in our collection.  These books do circulate often and students come back looking for other titles from the series.  I highly recommend this book.
