This book is a compact and abridged paperback edition of Botanica's Roses, The Encyclopedia of Roses also published by Konemann. Following in the same footprint as Botanica's other paperbacks. Each near 1000 pages! I bought this book as a companion to my other Botanica titles, though I rarely use it as most rose garden specimens are clearly identified. But it's great to carry along with you because it's not bulky.
