Last year, Patrick J. Gallagher published Loch Ness: From Out of the Depths, which was a collection of newspaper stories from the time of "the rise of the Loch Ness Monster" in 1933 and 1934. This year, he published a follow-up book, this one titled Loch Ness: Back into the Depths, and which has newspaper stories from 1935 to 1955.
The media loved the Loch Ness Monster in the 1930s, but that attention grew less and less in the '40s and '50s, as this book demonstrates. But, it was still reported quite often.
Throughout the book, you get to hear first-hand witness accounts reported in papers at the time, some people's thoughts as to what it(they) could be, coverage of "monster hunts," and much more. Overall, I really enjoyed this book. I enjoy reading old newspaper accounts of cryptids and it's nice to be taken back to the time when all of that was taking place.
You can get the book here.
