Borderlands 

The definitive exploration of the unknown and paranormal. BORDERLANDS contains hundreds of personal accounts of strange phenomena ranging from surviving mammoths in Siberia to intelligent clouds over New Zealand, from frozen frogs to plagues of murderous manhole covers. It also examines how and why these stories are reported and what they mean. The book sets out the scientific and psychological explanations for these phenomena, while remaining accessible to the casual reader. BORDERLANDS is the first complete critical survey of an extraordinary fast developing field.
