This book packs a lot of logos, over 2300 of them.
There are two points to note, though.
First, the designs are really experimental. There are lots of unusual logo applications. While the logos have style, they lack the elegance, and hence you won't see any big name client examples. Many I guess are designed for short term usage, for events, products, etc.
The other thing is, logos featured from the same design firm have similar styles. While they look different, they feel the same. When I'm looking at a series of logos, sometimes it's hard to tell them apart.
The large number of logos featured makes this a good resource for ideas. However, if you're looking for classy logos, this might not be the book for you.
The paperback actually has a cover that's quite hard, so I won't recommend the hardcover if it cost much more.
