I acquired some pages from an old copy of the International Journal of Cryptozoology (Vol.7 1988) which had some Loch Ness Monster articles. Three books were reviewed by Robert Rines, well known past President of the Academy of Applied Science; Richard Fitter, co-founder of the Loch Ness Phenomena Investigation Bureau and Jack Gibson of the Scottish Natural History Library.
They respectively reviewed Henry Bauer's "The Enigma of Loch Ness", Steuart Campbell's "The Loch Ness Monster: The Evidence" and Edward Armstrong's "Sticking My Neck Out!". The first two will probably be known to most readers, the last one was privately published and I looked at it myself some years back at this link. The pages are shown below and you click on them to get a larger, readable image.
