Peter Haining (whose book was published posthumously) has included a lifetime's worth of collected material - including newspaper articles covering a century of reports, a wide variety of reputable personages recounting their experiences with ghosts, eyewitness accounts from profressional journalists, a chapter on theories put forth by experts, a 'phantoms of the world' glossary at the end, and a lot more besides. This book is packed with well sourced evidence from the anecdotal to the professional investigators' of the paranormal. It is both engaging, informative and never boring (which all too many books on the 'afterlife' and 'hauntings', despite such a fascinating topic, are). Highly recommended.
P.S. If Peter Hainings compilation appeals, the book 'Night Side of Nature' by Catherine Crowe is sure to please. It was first published in 1848 and enjoyed great success for 50 years but now, unfortunately, is largely forgotten, though it most recently was reprinted by Wordsworth. Night Side of Nature is a paranormal tour de force. It is packed with almost 400 pages of accounts of apparitions of all varieties interspersed with arguments for and against investigators conclusions and opinions and is possibly the single best all around read on ghostly experiences. Catherine Crowe was also the first person to bring the word 'poltergeist' into the English language - the famous discussion is included in the Wordsworth publication which brings both volumes into one book. (A wee note - when Mrs Crowe writes of 'somnambules' she is basically referring to mediums of the day; when speaking of 'magnetism' she is referring what contemporary investigators might call 'psychic energy' or, more esoterically, 'magical sympathy').
