Loch Ness: From Out of the Depths: Original Newspaper Accounts of the Rise of the Loch Ness Monster, 1933-1934 by Patrick J. Gallagher. It came out in July of this year and looks like a good one!
Here's the book description:
"In 1933 'Nessie' erupted into the public consciousness with a deluge of sightings of 'something' in the waters of the 22 mile long and 700 foot deep Scottish loch. Since then the Loch Ness Monster has captured the public imagination more than any other cryptid creature. Gathered in this book are the original newspaper accounts from the year 1933 and 1934, when 'Nessie Fever' was at its height. Not just sightings, but plans for monster hunts and government responses to the appearances of this unknown creature are presented here. A number of the sightings documented here, possibly to 'mundane' to be sensationalized by the national press, are seeing print for the first time since the 1930s, after languishing in the archived pages of the small local newspapers in which they first appeared. Whatever your stance on the existence of the Loch Ness Monster, these accounts provide a fascinating insight into the happenings and opinions that swirled around Loch Ness in the early part of the 20th Century."
I don't know about you, but I for one love reading old newspaper accounts of cryptid sightings and "monster hunts." If you also enjoy that kind of stuff, get the book!
