Volume 17 of the Ecosystems of the World series is divided into two parts. Volume 17A provides a review of managed grasslands in different parts of the world and the varying ways in which they are managed. Volume 17B, ``Managed Grasslands: Analytical Studies'', edited by R.W. Snaydon, was published in 1987 and is mainly devoted to a discussion of ecological processes occurring in all managed grasslands. The two volumes provide a complete cross-section of current knowledge of the structure and function of managed grasslands throughout the world, including all the processes determining the productivity of these ecosystems.
