The Oak Island Compendium at theoakislandcompendium.com is the current iteration of the Oak Island research compendium originally created by Doug Crowell and Kel Hancock at Blockhouse Investigations, Nova Scotia. The original site continues to exist at oakislandcompendium.ca and remains the canonical archive for the Crowell and Hancock material, including the Les MacPhie Archives section, the Wonnacott Smith's Cove material, and an extensive body of original document analysis published under the Blockhouse Blog banner.
The current site is a relaunch operated by Charlotte Wheatley and a research collaborator, with the explicit permission of Crowell and Hancock. The site continues the Compendium project's editorial direction of separating fact from fiction in the Oak Island documentary record, and adds new investigative articles, document analyses, and topical research series. The operators connect to the broader Oak Island research community through the Oak Island Archeoastronomy Group and continue the research lines of the late Paul Wroclawski.
Both the original site (oakislandcompendium.ca) and the relaunch (theoakislandcompendium.com) are useful for Oak Island research. Researchers should consult both for full coverage of the material.
What this source documents
On the original Crowell and Hancock site (oakislandcompendium.ca): Les MacPhie Archives, Wonnacott Smith's Cove material, Blockhouse Blog articles covering original document analysis (newspaper articles, contemporary letters, the 90-foot stone investigation, the Liechti-cipher line of inquiry, dendrochronology updates), and topical files on Oak Island people, theories, and businesses.
On the current relaunch site (theoakislandcompendium.com): new investigative articles, document analyses, and topical research series produced under the current operators.
Why it matters
The Oak Island Compendium in both its original Blockhouse Investigations form and its current relaunch is one of the principal independent research surfaces on the Oak Island mystery, distinguished by its emphasis on primary documents and forensic argument over speculative theorising. The Crowell and Hancock work in particular is widely cited in subsequent Oak Island scholarship and television treatment, and the Compendium's investigations into the 90-foot stone and the Liechti cipher have shaped current research questions on those topics.
