The Secret History of the Conspiracy Document: From the Gemstone Files to the Photocopied Underground

Before the internet gave every rumour a global distribution network, conspiracy travelled on paper: typewritten, mimeographed, photocopied, stapled and passed from hand to hand. The history of modern conspiracy culture is also the history of the machines that made copying cheap.

The Paper Object

It usually arrived looking exhausted. The corner staple had begun to rust. A grey smear ran down one margin where a previous copier had failed to clean its glass. Sentences leaned towards invisibility, having survived eight or nine generations of reproduction. Somebody had underlined a name in red ink. Somebody else had written CHECK THIS beside a paragraph in which a banker, intelligence officer or billionaire was accused of controlling rather more of human history than seemed administratively possible.

Then came the introduction: “You have to read this.”

Long before the conspiracy podcast, the anonymous image-board post or the viral screenshot, there was the conspiracy document. It was not simply a container for an allegation. It was a recognisable genre with its own props and typography: monospaced type, erratic capitals, coded initials, diagrams, appended “evidence,” blacked-out passages and the indispensable promise that the reader was seeing something never intended for public eyes.

Its physical defects were part of its appeal. A cleanly printed book belonged to the official world. A blurred photocopy looked as though it had escaped from it.

The history of this material is therefore inseparable from the history of copying. Mimeographs, spirit duplicators, office photocopiers, cheap offset presses, postal mailing lists, cassette catalogues and bulletin board systems each widened the route by which unofficial information could travel. They enabled dissident politics, experimental art, underground literature, fandom and community publishing. They also enabled falsehoods to circulate without an editor, institution or identifiable author standing between claim and reader.

Before social media, belief moved at the speed of the nearest copying machine.

02 · The Original Leak

Before Xerox: Forgery as a Political Weapon

The conspiracy document predates the photocopier. Its deeper ancestor is the political forgery: a text manufactured to resemble the minutes, correspondence or private instructions of a hidden organisation.

No example demonstrates the danger more clearly than The Protocols of the Elders of Zion. First serialised in the Russian Empire in 1903, the document falsely presented itself as the record of secret meetings at which Jewish leaders planned global domination. The meetings never occurred and the supposed organisation did not exist. The document was an antisemitic fabrication assembled partly from earlier political satire and fiction.

In 1921, The Times journalist Philip Graves demonstrated that substantial passages had been plagiarised from Maurice Joly’s 1864 satire Dialogue in Hell Between Machiavelli and Montesquieu, a work that did not concern Jews. German and American investigators published further exposures during the 1920s. None stopped its circulation.

The United States Holocaust Memorial Museum describes the Protocols as the most widely distributed antisemitic publication of modern times. It has been repeatedly adapted to attach its old lie to new crises, enemies and technologies. Its survival is a grim lesson in the durability of the pseudo-document: once a forgery acquires the appearance of suppressed evidence, exposing its construction does not necessarily destroy its emotional usefulness.

Important distinction

The Protocols is not included here as a legitimate “alternative account.” It is a proven antisemitic forgery whose circulation helped incite and justify persecution. Its relevance is structural: it established the immensely influential pose of secret minutes recovered from a hidden ruling group.

The template would prove remarkably portable. Let a narrator speak with the confidence of an insider. Replace argument with alleged access. Present coincidence as coordination. Most importantly, make the document itself appear dangerous to possess. The reader is no longer merely reading a claim; the reader has been invited into the archive.

03 · Authority in Courier Type

Why a Document Feels Like Proof

Documents carry bureaucratic authority even when the bureaucracy behind them is imaginary. A typed memorandum looks as though it belongs to a chain of command. A case number suggests a larger filing system. Acronyms imply specialist knowledge. Redaction implies that somebody with power considered the hidden words dangerous.

Conspiracy documents exploit this visual language while reversing its meaning. A damaged copy becomes more persuasive than a pristine original because the damage tells a story: this was copied hurriedly, removed without permission, rescued from destruction or passed through enough hands to defeat suppression. Bad reproduction does not weaken the evidence. It dramatises it.

Political scientist Michael Barkun uses the term stigmatized knowledge for claims that exist outside institutions regarded as capable of validating knowledge. In conspiratorial systems, rejection by universities, government departments or established media may be interpreted not as disproof but as evidence that those institutions are protecting themselves. The claim becomes attractive partly because respectable authority refuses it.

Barkun also describes improvisational millennialism: the mixing of beliefs and sources that were once separate or even incompatible. Intelligence operations can be joined to UFOs, secret societies, biblical prophecy, banking theories, psychic research and medical anxieties. The conspiracy file is ideal for this process because it is expandable. Another clipping, memorandum or annotated diagram can always be added.

This is why conspiracy documentation resembles collage. Its force often comes from proximity rather than proof. Two names placed on the same chart begin to look connected. Four newspaper extracts arranged on one page appear to describe a pattern. In its 2018 exhibition Everything Is Connected: Art and Conspiracy, the Metropolitan Museum of Art examined how surveillance photographs, diagrams, strings of association and paranoid networks had become an artistic language in their own right. The “look” of conspiracy can communicate before any claim has been read.

Case Study: The Gemstone File

If the modern conspiracy document had to be represented by a single artefact, the Gemstone File would make a strong candidate. It has an uncertain origin, disputed authorship, several incompatible versions and a plot expansive enough to make an airport thriller appear restrained. It also became famous through photocopying rather than conventional publication.

The material is attributed to Bruce Porter Roberts, an inventor who claimed that Howard Hughes had stolen his process for manufacturing synthetic rubies. During the late 1960s and early 1970s, Roberts wrote a mass of letters and notes in which this personal grievance expanded into an account of hidden twentieth-century history.

Even the size and physical form of the original archive remain contested. Estimates range from approximately 350 surviving photocopied pages to more than a thousand original pages. Stephanie Caruana later described Roberts writing in ballpoint pen on yellow legal pads. Other researchers reported different paper and pencil originals. No complete, independently authenticated master file has emerged.

That uncertainty is not incidental to the Gemstone story. It is the story.

Mae Brussell and the Folder

In 1972, Roberts reportedly gave several hundred copied pages to Mae Brussell, the radio broadcaster and assassination researcher best known for compiling an enormous index to the Warren Commission report. According to one account, Brussell created “the Gemstone File” in the most literal fashion possible: she placed the papers in a manila folder and wrote Gemstone on its tab.

The name later accumulated alternative explanations, including Roberts’ supposed habit of sending artificial gemstones with his correspondence. Even the title therefore exists in the same unstable territory as the text itself: partly documented, partly remembered and repeatedly retold.

The Skeleton Key

The decisive act of transformation came in 1975. Caruana condensed parts of the material, along with her recollections of Roberts and related correspondence, into a 23- or 24-page typescript titled A Skeleton Key to the Gemstone File.

Copies began appearing on college campuses and in alternative bookshops across North America. Caruana said that she produced several editions during the spring of 1975, giving them away or selling them for three dollars—the approximate cost of reproduction. The anonymous-looking digest was short enough to copy, dramatic enough to recommend and just obscure enough to feel forbidden.

According to the detailed circulation history maintained by the Grand Lodge of British Columbia and Yukon, the surviving “file” consists largely of photocopies of photocopies. Some carried Brussell’s marginal notes. The originals had apparently been returned to Roberts and may have disappeared with the rest of his estate after his death in 1976.

What the File Alleged

The Skeleton Key claimed that Aristotle Onassis stood at the centre of a vast conspiracy involving Howard Hughes, the Kennedy family, organised crime, American intelligence and a succession of political assassinations. It alleged that Hughes had been kidnapped, incapacitated and secretly controlled; that major political careers were being directed from behind the scenes; and that Lee Harvey Oswald had served as a patsy rather than the assassin of President John F. Kennedy.

These were allegations, not established findings. Researchers who examined the available pages found contradictions, unsupported assertions and claims that could be disproved from the public record. Yet factual weakness did little to diminish the document’s narrative power. It transformed scattered anxieties about wealth, assassination, intelligence agencies, organised crime and political corruption into a single all-explaining system.

Writers James McConnachie and Robin Tudge would later call it “the original mega-conspiracy theory.” The phrase fits because Gemstone did not merely propose a hidden plot. It proposed that apparently separate plots were components of one machine.

Mutation by Reproduction

The document did not remain stable. A heavily altered version appeared in Hustler in 1979. A New Zealand continuation known as the Kiwi Gemstone or Opal File followed in 1988. Different researchers claimed knowledge of the originals, challenged Caruana’s authorship or produced competing transcriptions.

Mike Gunderloy, publisher of the zine-review magazine Factsheet Five, collected and redistributed several Gemstone variants through the 1980s. Books edited or written by Jim Keith, Gerald Carroll, Kenn Thomas, David Hatcher Childress and Caruana later attempted to organise the material. In January 2006, a transcription of more than 350 pages was placed online.

After three decades of envelopes, photocopies and mail-order catalogues, the file had become a blog.

  • 1968–75 Roberts writes the letters and notes later associated with Gemstone.
  • 1972 A batch of copied pages reportedly reaches Mae Brussell.
  • 1975 Caruana’s photocopied Skeleton Key begins circulating.
  • 1979 A substantially altered version appears in Hustler.
  • 1988 The Kiwi Gemstone or Opal File extends the mythology.
  • 1990s Books and zine networks attempt to organise competing versions.
  • 2006 A lengthy transcription appears online.

The name should not be confused with G. Gordon Liddy’s separate Operation Gemstone, the proposed programme of political espionage and disruption connected to Nixon’s re-election campaign. That other Gemstone—and its path towards Watergate—is explored in the Hellwood feature Operation Gemstone: The Bizarre Dirty-Tricks Plan That Led to Watergate.

05 · Instruments of Production

The Machines That Made the Underground

The Gemstone File became possible because document reproduction had undergone a quiet revolution.

Stencil duplicators and mimeographs had already allowed political groups, schools, churches and science-fiction enthusiasts to create small print runs without a commercial press. During the 1930s, fans used stencil printing to make the amateur magazines that gave the word fanzine to the language. Post-war poets, radicals and artists inherited the same machinery.

Historian Gabriel McKee’s study Office Copying Technology in the Flying Saucer Subculture quotes activist Dwight Macdonald comparing the American radical movement’s mimeograph machines to the machine guns of the Russian Revolution. They were, in Macdonald’s phrase, “the instruments of production.” Whoever controlled the duplicator could manufacture a public.

“The mimeographs were the instruments of production.” Dwight Macdonald, recalling American radical publishing

Chester Carlson produced the first xerographic image in 1938. After years of development with the Haloid company, the Xerox 914 was introduced in 1959. It was not a small machine—it weighed hundreds of pounds—but it made automatic copies on ordinary paper. The Smithsonian’s National Museum of American History describes the 914 as the machine that revolutionised document copying.

The change was cultural as well as mechanical. A user no longer needed to cut a stencil or prepare a printing plate. Existing pages, photographs, newspaper columns and handwritten notes could be reproduced together. The copier did not merely duplicate writing; it made appropriation, collage and instant republication ordinary office activities.

UFO researchers were early and enthusiastic users. Newsletters produced by organisations such as the Aerial Phenomena Research Organization created networks in which sightings, rumours and theories could be compared outside newspapers or academic journals. McKee describes these mimeographed publications as the backbone of early UFO literature. Gray Barker’s The Saucerian, launched on a spirit duplicator in 1953, helped turn the Men in Black and other marginal stories into durable folklore.

The same machinery carried avant-garde poetry, trade-union arguments, fan writing and conspiracy. Technology did not choose the message. It simply abolished more of the cost of sending one.

The Photocopied Underground

By the 1970s and 1980s, an alternative information economy existed beneath mainstream publishing. Its storefront was often a classified advertisement. Its headquarters might be a spare bedroom. Its financial infrastructure consisted of dollar bills concealed in envelopes and cheques made payable to names that sounded only slightly more official than the publications they produced.

The typical objects were stapled zines, single-sheet newsletters, mail-order book catalogues, lecture transcripts, cassette recordings and packets of clippings. Readers did not simply consume this material. They copied it, annotated it, reviewed it, recommended it and supplied new addresses. The network was slow, but it was participatory.

Factsheet Five became one of its great switching stations. Mike Gunderloy founded the publication in Boston in 1982 with a spirit-duplicated run of just 50 copies. The premise was brilliantly practical: short reviews of privately produced publications, accompanied by the addresses needed to obtain them.

By the end of the decade, Factsheet Five connected thousands of publishers whose work ranged across music, politics, art, science fiction, personal confession, mail art, occultism and conspiracy. It provided discoverability before search engines. A reader might enter through a punk zine and emerge three addresses later ordering a dossier about political assassinations. Gunderloy’s own collection eventually grew to more than 10,000 zines and mail-art items, now held by the New York State Library.

Gemstone fitted this ecosystem perfectly. It had no stable commercial edition, no universally accepted text and no central authority. Its variants could be listed, traded and compared like evidence from an investigation that never formally ended.

Milton William Cooper’s 1991 book Behold a Pale Horse belonged to the next stage of this culture. It assembled UFO claims, political suspicion, apocalyptic interpretation and alleged secret-government material into what Barkun classified as a highly influential “superconspiracy.” Cooper reinforced the book through shortwave broadcasting, public lectures and cassette distribution. Some associated material had already travelled through ParaNet, an early computer network devoted to UFO and paranormal discussion.

The old and new systems overlapped. A modem user downloaded a text, printed it, copied it and mailed it to somebody without a computer. A shortwave listener ordered a cassette. A cassette led to a book. The book supplied addresses for newsletters. Media did not replace one another neatly; they formed a contraption.

Danny Casolaro’s unfinished “Octopus” investigation shows how the archive itself could become the narrative. Casolaro believed that disputes surrounding the PROMIS computer software connected to a much larger network of intelligence operations, political scandals and organised crime. His death in 1991 generated further suspicion and a continuing trail of books, records and investigations. The U.S. National Archives now holds Department of Justice files concerning Inslaw, Casolaro’s theories and the investigations into his death.

Other institutional archives are beginning to preserve the material once dismissed as disposable. Duke University’s Parker Anderson collection of conspiracy theory research contains pamphlets, correspondence, catalogues and copied clippings gathered largely during the 1990s. Such collections confirm that the photocopied underground was not a vague legend. It was a physical network, and it left paper behind.

07 · Dial-Up Revelation

From Photocopier to Modem

The transition to digital conspiracy culture did not begin with social media. It began with the modem’s shriek.

Bulletin board systems allowed users to dial directly into computers hosting message boards and downloadable files. Networks such as ParaNet performed much the same function as mail-order newsletters: they gathered people with specialised interests, promised access to material neglected elsewhere and allowed documents to move between strangers.

The audience was still comparatively small. Access required equipment, patience and at least some technical knowledge. Connections were slow. Long documents were inconvenient to read on screen and frequently ended up on paper. Yet the BBS introduced a decisive change. Once a file existed digitally, the cost of making the next copy approached zero.

Factsheet Five crossed the same border. Gunderloy operated a zine-related BBS, while Jerod Pore’s Factsheet Five Electric used the Usenet group alt.zines. The directory of physical publications had become part of the network it once foreshadowed.

The physical document’s visual tricks survived digitisation. Forwarded emails warned readers to save them before deletion. PDFs used official-looking seals, numbered paragraphs and scanned signatures. Screenshots detached statements from their original context. Posts announced that mainstream search engines were suppressing information that remained, somehow, readily available through mainstream search engines.

The machine had changed. The theatre of forbidden access had not.

QAnon’s “drops” represent an extreme version of this development: short, cryptic posts published under the identity of a supposed government insider, then decoded, arranged and redistributed by a large participatory audience. The original fragments were less important than the interpretive machinery built around them.

A study presented at the 2022 International AAAI Conference on Web and Social Media assembled 4,949 supposedly canonical Q drops from six aggregation sites. The sites did not fully agree on which posts belonged to the canon, and linguistic analysis found statistically significant indications that the material had more than one author.

The resemblance to Gemstone is striking without requiring the two phenomena to be identical. Both developed unstable canons. Both offered the voice of an insider. Both encouraged readers to perform connections themselves. Both acquired competing custodians who claimed to possess the correct version. Authorship disputes did not end participation; they produced more material for it.

08 · Copy of a Copy of a Copy

The Document Is the Message

A conspiracy document is rarely a fixed text. It is a circulation system.

The Protocols changed across languages and political settings while preserving its antisemitic core. The Gemstone File splintered into summaries, rewrites, magazine versions, continuations, books and online transcriptions. Zines crossed between photocopying and computer networks. Digital drops were removed from transient message boards, copied into aggregators, interpreted in videos and returned to the internet as screenshots.

Each act of copying appears to move the material farther from an identifiable origin. Paradoxically, that distance may enhance the aura of secrecy. Missing context becomes proof of suppression. Uncertain authorship becomes protection for the source. The absence of a definitive version allows every custodian to promise a more complete one.

This does not mean that all unofficial documents are false or that independent publishing is inherently suspect. Copying technology has allowed whistleblowers, dissidents, artists, minority communities and political movements to bypass hostile gatekeepers. The photocopier is neither democratic nor paranoid by nature. It is promiscuous. It reproduces whatever is placed on the glass.

That is why the history matters. Conspiracy claims do not spread only because of what they say. They spread because of the experience they offer: discovery, initiation, participation and the intoxicating possibility that the reader has received a fragment of the real story.

Today’s leaked-looking PDF, anonymous screenshot or post accompanied by “download this before it disappears” is the direct descendant of the dog-eared photocopy sold for three dollars outside an alternative bookshop in 1975. The staple has vanished. The invitation remains.

The document was never merely carrying the conspiracy. The document was teaching people how to enter it.

Frequently Asked Questions

What was the Gemstone File?

The Gemstone File was a collection of conspiracy writings attributed to Bruce Porter Roberts. Its best-known form was Stephanie Caruana’s short 1975 digest, A Skeleton Key to the Gemstone File, which linked Howard Hughes, Aristotle Onassis, the Kennedy family, organised crime and American intelligence in a single alleged conspiracy.

Who wrote A Skeleton Key to the Gemstone File?

The digest is generally attributed to writer Stephanie Caruana, who said she based it on Roberts’ letters, conversations with him and material she had seen through researcher Mae Brussell. Competing authorship claims exist, but no rival account has been conclusively established.

How did conspiracy documents spread before the internet?

They travelled through photocopies, mimeographed newsletters, alternative bookshops, mail-order catalogues, cassette exchanges, classified advertisements, public lectures and personal correspondence. During the 1980s and early 1990s, bulletin board systems and Usenet began connecting these physical networks to digital distribution.

Why did badly copied documents appear convincing?

Blurred type, handwritten annotations and degraded images could make a document appear illicit or difficult to obtain. The damage implied that it had passed through many hands or escaped an official archive, turning poor reproduction into part of the document’s claim to authenticity.
