There is a compendium of transcripts, newspaper clippings, signed affidavits and extracts of a book 'The story of Oak Island 1895' in a .pdf file by Les MacPhie 2014, that isn't copyrighted as far as I can tell. This gives a meaty story of the search for 'Captain Kidd's treasure' from 1849 to around 1895 and mentions the key aspects of the narration given in the current Curse of Oak Island series. Thus you have the story of McGinnis making the Money Pit discovery, the Onslow and Truro companies, the Oak Island Association and the Halifax companies, each promising investors that the big discovery will be made in the next 20 feet or $2,000 investment. The flood tunnels in Smith Cove, the other tunnels in the middle shore, coconut matting, traces of parchment recovered, building a coffer dam, the carved stone from 90ft - it's all there. In fact apart from the Nolan Cross and the swamp, one wonders if the Restalls, Nolan, Blankenship and Laginas investigations have added anything to the Oak Island story in the last 100 years (besides obliterating the landscape).
The file is 130 pages long (takes a while to load), I'd recommend starting with the book at page 91.
