Text produced by SCP-1804 may only be copied as part of an 
authorized experiment, and such copies must be destroyed upon 
test completion. After any testing, test subjects must be given Class- 
A amnestics to remove knowledge of the contents of any anomalous 
text documents. 


Description: SCP-1804 is a fully functional Underwood Model #5 
Typewriter with a U.S. key layout, manufactured at some time 
between 1925 and 1928. The machine shows signs of wear 
consistent with relatively frequent use, as well as several parts that 
seem to have been replaced and/or serviced during its lifetime. No 
part of the mechanism is atypical for this model of typewriter, and 
the materials used in its construction show no abnormalities. 


When SCP-1804 is used to produce text, the text produced may 
exhibit anomalous properties. Anomalous effects will not be present 
if the majority of text is not original to the document being typed. If 
such properties are present, they will manifest by triggering 
abnormal cognitive and/or emotional reactions in subjects upon 
reading the text. Such effects appear to require the subject’s 
comprehension of the anomalous text and will affect the typist as 
well as subsequent readers. The exact nature of these effects 
appears to vary based on the semantic content of the text, the state 
of mind of the typist, and the intended purpose of the text. 


When text produced by SCP-1804 shows anomalous properties, 
those properties will manifest in any copies that retain the exact 
same semantic meaning as the original typewritten manuscript. This 
includes photocopies, transcriptions, and OCR scans. Translations 
into other languages and audio reproductions of anomalous text 
have, to date, shown no anomalous properties.

Document EX-1804-111A: Experiment Log 
for SCP-1804 
Test 011 
Designation: N/A 
Date: / /20 


Subject: D-12758, a bilingual male fluent in 
English and Spanish. 


Procedure: Subject is told to transcribe the 
poem "Jabberwocky" by Lewis Carroll (1872) 
using SCP-1804. 


Results: Resulting document shows no 
anomalous properties. 


Notes: Confirms the fact that SCP-1804 only 
produces anomalous text when the content is 
substantially original. — Dr. R. 

Test 012 

Designation: SCP-1804-27B 


Date: / /20 


Subject: D-12758, a bilingual male fluent in 
English and Spanish. 


Procedure: Subject is told to translate the 
poem "Jabberwocky" by Lewis Carroll (1872) 
from English to Spanish using SCP-1804. 


Results: All persons reading D-12758's 
translation become convinced that the poem in 
question is an original Spanish composition. 
After typing the original text, D-12758 himself 
denied authorship and claimed it was an old 
folktale his grandmother read to him. When 
shown the original 1872 work, D-12758 
theorized that the author plagiarized the 
ancient Spanish original. 


Notes: Apparently the act of translation 
confers enough original content to trigger 
SCP-1804's effect — Dr. R. 


Test 018 
Designation: SCP-1804-29B 
Date: / /20 


Subject: D-12758, a bilingual male fluent in 
English and Spanish. 


Procedure: Subject is told to type an original 
recipe on SCP-1804. 


Results: Subject types a recipe for "Mom's 
Polenta".2 Subjects who read the recipe 
develop an aversion to corn and corn-meal 
based foodstuffs to the point of nausea. No 
anomalous effects were noted when the recipe 
was prepared and served to subjects who had 
not read the recipe. 


Notes: SCP-1804's effect seems to be 
influenced quite a bit by the psychological 
state of the typist.— Dr. R. 


Test 037 

Designation: SCP-1804-101B 
Date: /12/20 - /19/20 
Subject: D-56674 


Procedure: Over the course of one week 
subject was instructed to maintain a daily diary 
using SCP-1804. 


Results: The psychological state of the 
subject progressively degraded, showing 
worsening signs of depression and paranoid 
delusion. By day seven, subject was 
convinced that the Foundation was replacing 
parts of her body with pieces of SCP-1804.3 
Subjects reading SCP-1804-101B develop 
similar symptoms, progressing similarly as 
each day's document is read. 


Notes: SCP-1804's effect appears to become 
more profound with repeated exposure as well 
as with document length. It helps explain why 
the users of SCP-1804 seem to end up much 
worse off than those simply exposed to 
SCP-1804's documents— Dr. R. 


Test 048 
Designation: SCP-1804-106B 


Date: / /20 


Subject: D-11275 


Procedure: Subject instructed to compose a 
fictional narrative of at least 1000 words on 
SCP-1804. 


Results: Subject composes a vignette of a 
sexual nature detailing a homosexual 
encounter between [REDACTED] and 
[REDACTED] from the U.S. television series 
[REDACTED]. Subjects reading this narrative 
all express a sense of incompleteness about 
the "story" in SCP-1804-106B, as well as 
dissatisfaction in the execution.4 Subjects will 
subsequently attempt to "do it right," writing 
their own narratives based loosely on 
SCP-1804-106B and [REDACTED]. To date, 
the longest narrative so-produced is a 
100,000-word trilogy produced by Dr. S. 

after accidental exposure.9 


Notes: It'd be interesting to see if there are 
higher-order effects from compositions that are 
themselves generated from a compulsion due 
to SCP-1804's effect— Dr. R. 


Test 049 

Designation: SCP-1804-107B 
Date: / /20 

Subject: D-22138 


Procedure: Subject exposed to 
SCP-1804-106B, then instructed to compose a 
fictional narrative of at least 1000 words on 
SCP-1804. 


Results: [REDACTED] 


Notes: Jurns out that was not a great idea.—

Addendum 2: 
+ Document RL-1804-101A 


Document RL-1804-101A: Recovery Log for 
SCP-1804: Selected list of documents 
produced by SCP-1804 prior to containment. 


Designation: SCP-1804-1A 


Summary: SCP-1804-1A was a newsletter of 
the “[REDACTED] Society” written in / /1973 
byMrs.L G__ . The newsletter was 
reproduced via a spirit duplicator® running to 
approximately 150 copies. The newsletter 
compiles a number of popular conspiracy 
theories of the time, particularly those involving 
the assassinations of various political figures. 


Anomalous Effects: Effects are confined to 
subjects who read SCP-1804-1A in whole and 
in order.’ Those who are affected begin to 
show typical signs of paranoid schizophrenia, 
including delusions of persecution focusing 
around one or more public figures. Symptoms 
progress over time, and subjects are likely to 
plan and carry out violence against the public 
figures that are the targets of their fixation. 


Containment Notes: SCP-1804-1A9 was 
recovered by the foundation in 198119 after 
several detectives involved in the investigation 
of the murder of by were 
diagnosed with similar psychological problems 
at around the same time. The copy of 
SCP-1804-1A [REDACTED] from evidence 
was replaced by an edited non-anomalous 
version of the newsletter. To date, copies of 


SCP-1804-1A have been recovered or 
confirmed destroyed. 


Designation: SCP-1804-2A, SCP-1804-3A 


Summary: SCP-1804-2A, SCP-1804-3A are 
two undated documents authored by Mrs. L 

G in her capacity as a History teacher at 
[REDACTED] High School in [REDACTED] 
between 1961 and 1975. Both were 
reproduced via a spirit duplicator similar to 
SCP-1804-1A, both are multiple-choice 
quizzes. SCP-1804-2A concerns events of the 
U.S. Civil War and SCP-1804-3A concerns the 
period of the Great Depression. 


Anomalous Effects: All subjects, after 
reading either document, will answer each 
question in exactly the same manner. A 
subject will answer 19 of 20 questions 
correctly on SCP-1804-2A and 18 of 20 
correctly on SCP-1804-3A. Subjects will 
answer the same questions incorrectly, and 
with the same responses. All subjects, 
regardless of prior knowledge of American 
history, will believe all provided answers 
(including incorrect ones) are accurate. No 
attempt to convince an affected subject 
otherwise has been successful. 


Containment Notes: SCP-1804-2A1! and 
SCP-1804-3A12 were recovered along with 
over 300 other non-anomalous documents 
authored by Mrs. G as part of the 
investigation of SCP-1804-1A.13.14 


Designation: SCP-1804-8A 


Summary: SCP-1804-8A is a letter to the 


editor of the [REDACTED] newspaper in 
[REDACTED] written by Mr.C OD 

published on / /20 . The letter expresses 

D __ 's frustration with corruption in city 
government, with particular attention paid to 
cronyism in awarding a liquor license to the 
"Bucking Bronco" saloon despite numerous 
complaints about solicitation and violations of 
city ordinances regulating "gentlemans' clubs." 


Anomalous Effects: Subjects reading the 
letter will develop a strong aversion to public 
displays of a sexual nature, especially any 
form of commercial transaction involving 
sexuality. Subjects will become convinced that 
all such activity is always illegal regardless of 
the specific statutes in their current jurisdiction. 
When confronted directly by someone 
engaged in such a practice, the subject will be 
hostile and may respond violently. 


Containment Notes: Two days after the 
publication of SCP-1804-8A, a riot occurred in 
which the "Bucking Bronco" saloon was 
burned to the ground and a mob converged on 
City Hall and proceeded with an attempted 
lynching of [REDACTED] Foundation agents 
arrived as authorities were attempting to 
suppress the riot and began containment with 
aerosol dispersal of Amnesiacs. When agents 
converged on the address where 
SCP-1804-8A originated, a shootout between 
Mr. D and MTF agents ensued. The MTF 
team recovered all copies of SCP-1804-8A in 
the aftermath. separate anomalous text 
documents were recovered from the remains 
ofMr.D __'s residence, and typographic 
analysis showed that all were written on 
SCP-180415, which was also recovered at this 
time. 


Designation: SCP-1804-13A 


Summary: SCP-1804-13A is a fraudulent 
suicide note written by Mr.A C on / 

/1939 as part of an elaborate scheme to 
avoid [REDACTED].A C was 
discovered by authorities living under an 
assumed name in [REDACTED] and 
extradited / /1947 to face trial. Despite 
significant evidence, including eye-witness 
testimony to his true identity, he was acquitted 
in / /1947. Shortly after his release 
[REDACTED] by agents of [REDACTED]. The 
body was never recovered. 


Anomalous Effects: Subjects who read 
SCP-1804-13A’s suicide note are convinced 
that Mr. C did commit suicide on / /1939, 
despite all evidence to the contrary. Affected 
subjects believe that the man apprehended, 
put on trial, and eventually assassinated was 
some other person who was the victim of 
mistaken identity. The affected persons 
included the judge and jurorsatA C  ’s 
trial, as wellasA C himself. 


Containment Notes: SCP-1804-13A was not 
reproduced outside court documentation. All 
known surviving copies of SCP-1804-13A 
have been recovered. 


Designation: SCP-1804-14A, SCP-1804-15A, 
SCP-1804-16A 


Summary: SCP-1804-14A, SCP-1804-15A 
and SCP-1804-16A are all internal 
memoranda giving executive-level intelligence 
summaries of [REDACTED] occurring in 
[REDACTED] in the lead-up to World War II. 


They were authored by Mr.A C_ ,aclerk 
in the United States War Department from / 

/1932 to / /1939. They appear to be part of 
a Ongoing series of such summaries, all 
dealing with [REDACTED] use of paranormal 
[REDACTED]. 


Anomalous Effects: The three documents so- 
far recovered have similar effects. The reader 
will experience violent disgust at the 
document’s subject matter, coupled with an 
existential disbelief in the topics presented. 
Not only will the subject disbelieve the 
possibility that [REDACTED] might have some 
efficacy, they will disbelieve that [REDACTED] 
would have even attempted to 
[REDACTED].'6 In some cases, this disbelief 
carries over into a fervent disbelief in all 
paranormal phenomena. 


Containment Notes: While over 100 of these 
memoranda were authored by Mr. C prior 
to / /1939, most appear to have been 
destroyed during World War II. Research 
efforts to recover any remaining copies from 
U.S. government archives are ongoing. 


Designation: SCP-1804-58A 


Summary: A pseudonymous 5000-word short 
story appearing in the Winter 1957 edition of 
[REDACTED] entitled "The Creeping Chaos of 
Chi Centaurus." The story concerns the 
invasion of a Galactic Republic by an invisible 
and unnameable hostile force that literally rots 
the societal structure from within. The story is 
an obvious allegory for the commonly 
perceived Communist threat in the United 
States of the era. 


Anomalous Effects: Readers of the story will 
develop a strong phobia regarding dirt and 
germs, often expressing an unfounded belief 
that the interiors of objects, including people, 
are rotting away. Subjects will often 
anthropomorphize decay and sickness to the 
point where they are convinced that "the 
forces of entropy" are continually watching 
them. 


Containment Notes: SCP-1804-58A17 had 
been in containment since early 1958, and all 
editions of the Winter 1957 edition of 
[REDACTED] were confiscated and pulped 
excepting copies retained for testing. 
Connection to SCP-1804 and identity of the 
author was not established until the death of 
Mrs.W K_ in20 .Mrs.K_ was the 
surviving spouse of Mr.F K _ ,aminor 
science-fiction author published in various 
magazines during the 1950s.18 Mrs. K 
bequeathed her late husband's papers to the 
University of [REDACTED] resulting in 10 
casualties and a police standoff with a 
graduate student with a high-powered rifle. 
After the incident, the Foundation recovered 
the papers from the University and identified 
127 separate short stories composed on 
SCP-1804 between 1955 and 1958, all 
showing anomalous properties to some 
degree. of these stories had seen 
publication, but only SCP-1804-58A had made 
it into print without editing, and retained 
SCP-1804's effect. 


Footnotes 

1. Anomalous documents produced prior to containment shall be 
identified SCP-1804-{nnn}A, and documents produced after 
containment shall be identified SCP-1804-{nnn}B, where {nnn} is the 
next sequential identifier. 


2. D-12758 had been convicted of murdering his mother and her 

live-in boyfriend. 

3. For example, she believed her teeth were typewriter keys, her 

fingers type-bars, and her tongue had become a spool of typewriter 

ribbon. 

4. Acommon complaint is, "That's not how [REDACTED] would act," 

even from persons who had never seen the [REDACTED] television 

series. 

5. Drs: revealed in subsequent interviews that [REDACTED] 

was her favorite series and that, "curiosity got the better of her." 

Given the benign nature of SCP-1804-106B's effect, and an 

acceptable post-exposure psychological workup, Dr. S. was 

only subject to administrative discipline and reassignment. 

6. aka “Ditto Machine” 

7. The newsletter is over 30,000 words long, so effective exposure 

prior to containment was limited. 

8. No particular relationship between targets of this fixation and 

SCP-1804-1A have been found 

9. Originally designated SCP- -1. 

10. Recovery of SCP-1804-1A predates the recovery of SCP-1804 

by years. 

11. Original designation SCP-  -2 

12. Original designation SCP-  -3 

13. It it theorized that the majority of the non-anomalous documents, 

all teaching materials for Mrs.G _—_'s American History class, were 

composed on SCP-1804 but lacked enough original content to 

trigger an anomalous effect. 

14. At the time of recovery it was believed Mrs. G was the 

source of the anomalous effect. She was recovered from an 

inpatient psychiatric facility by the Foundation and designated SCP- 
. She was uncooperative and, due to her psychological state, was 

unable to provide the Foundation with any usable data before 

[REDACTED] resulting in her termination.
