The Peak District, Britain's first national park, is a land of great natural beauty, visited by millions of people every year. This New Naturalist volume on the region highlights the wonder and magic of its windswept vistas, rock formations, storied history and fantastic wildlife, revealing its ecological foundations, showing how it has fared over the centuries and projecting what the future might hold. As a botanist and ecologist who has spent her working life in the Peak District, Penny Anderson brings an ecological perspective, viewing the habitats and their species as an interconnected whole linked to the development of the landscape through its geology and geomorphological processes, while simultaneously weaving in human history and local myths and legends to bring to life the evolution of the area. The Peak District is a special place at an ecological crossroads where many northern and southern species meet. It has splendidly rich wildlife, varied ecosystems and a long history of human interaction with the land, and this book gives a flavour of its diversity and value.

In early 1986, one of us (D.M.S.) was constructing an artificial intelligence system to design algorithms, and the other (A.P.A.) was getting started in program transformations research. We shared an office, and exchanged a few papers on the systematic development of algorithms from specifications. Gradually we realized that we were trying to solve some of the same problems. And so, despite radical differences between ourselves in research approaches, we set out together to see what we could learn from these papers. That's how this book started: a couple of graduate students trying to cope with The Literature. At first, there was just a list of papers. One of us (D.M.S.) tried to cast the papers in a uniform framework by describing the problem spaces searched, an approach used in artificial intelligence for understanding many tasks. The generalized problem space descriptions, though useful, seemed to abstract too much, so we decided to compare papers by different authors dealing with the same algorithm. These comparisons proved crucial: for then we began to see similar key design choices for each algorithm.

Wings of Hope is the inspirational story of Fred Schroder's journey with his shocking diagnosis of inoperable lung cancer. It describes how we, as husband and wife, responded to his cancer treatments and temporary healing. We were very grateful for the gift of time of fourteen months to prepare ourselves for his hospice care. In order to cope with the care giving challenges, we formed a support team of doctors, nurses, lawyers, chaplains, ministers, family, and friends. These remarkable people accompanied us on our struggle with life and death.
