How NewThoughtHistory.org Selects, Evaluates, and Cites Historical Sources

NewThoughtHistory.org is an independent historical reference project documenting the people, organizations, books, publications, ideas, and events associated with the New Thought movement.

Sources are fundamental to that work.

A historical statement becomes more useful when readers can determine where the information came from, examine the underlying evidence, and distinguish a contemporary document from a later interpretation.

Our objective is therefore not simply to add references to the bottom of an article.

Our goal is to make important historical claims traceable.

This Sources & Citation Policy explains what sources we use, how we evaluate them, how citations are presented, and how we handle quotations, archives, digital materials, disputed claims, and incomplete evidence.

1. Why We Cite Sources

Citations serve several purposes.

They allow readers to:

verify factual claims;
locate original documents;
distinguish evidence from interpretation;
identify the origin of quotations;
examine competing historical accounts;
discover additional research;
and understand how a conclusion was reached.

A citation is therefore more than a formality.

It is part of the historical evidence supporting an article.

Whenever practical, a reader should be able to follow a citation from NewThoughtHistory.org to the source on which an important claim depends.

2. Our Core Citation Principle

Our basic rule is:

Important historical claims should be supported by sources appropriate to the type of claim being made.

Different claims require different evidence.

For example:

A historical book’s title page may establish its publication information.

A letter may establish that two people corresponded.

A newspaper advertisement may establish that a lecture was advertised.

An organization’s minutes may establish that a meeting occurred.

A scholarly book may help explain why historians consider an event important.

No single type of source is ideal for every historical question.

3. Primary Sources

Primary sources are central to NewThoughtHistory.org.

These may include:

books published during the period being studied;
letters;
diaries;
manuscripts;
periodicals;
newspapers;
sermons;
lectures;
pamphlets;
advertisements;
directories;
photographs;
conference proceedings;
organizational records;
legal records;
census records;
and other contemporary documents.

Where practical, we cite the original item or a reliable digital reproduction of it.

Primary sources are especially valuable for establishing what historical participants:

wrote, taught, published, advertised, reported, remembered, or recorded.

They are not automatically neutral or factually complete.

Their evidentiary value depends on the question being asked.

4. Primary Sources Are Cited as Evidence, Not as Automatic Truth

A primary source demonstrates that a statement or representation existed.

It does not necessarily prove that everything contained within it was objectively correct.

For example, if a historical New Thought periodical reports that a practitioner experienced a healing, the periodical can establish that the account was published.

It may also help establish what practitioners believed.

It does not, by itself, establish the medical cause of the reported recovery.

Similarly, a memoir may provide direct evidence of how someone remembered an event without proving that every detail of the memory was accurate.

Our citations should preserve this distinction.

5. Secondary Sources

Secondary sources help interpret and contextualize historical evidence.

Preferred secondary sources include:

scholarly monographs;
university press books;
peer-reviewed journal articles;
academic research projects;
dissertations and theses when useful;
scholarly encyclopedias;
and works by historians or religious-studies scholars with demonstrated expertise.

Secondary sources are particularly useful for:

historical context

historiography

interpretation

comparison

and

identifying disputed questions.

Where scholars disagree significantly, citations should make it possible for readers to identify which interpretation is being discussed.

6. Institutional Sources

New Thought organizations maintain valuable records concerning their own histories.

These sources may include:

official histories;
biographies;
archival collections;
historical magazines;
organizational timelines;
photographs;
sermons;
correspondence;
and administrative records.

Such material can be indispensable.

However, institutional sources are not automatically treated as independent historical assessments.

When perspective matters, wording should make the source clear.

For example:

“According to Unity’s historical account…”

or:

“The International New Thought Alliance records…”

is preferable to silently presenting an institutional interpretation as universal historical consensus.

7. Libraries and Archives

We strongly prefer materials held or described by identifiable libraries, archives, universities, museums, and historical repositories.

Examples may include:

university special collections;
the Library of Congress;
institutional archives;
historical societies;
digitized newspaper repositories;
manuscript collections;
and established digital libraries.

Archival provenance adds valuable context.

Whenever available, an archival citation may include:

creator

document title or description

date

collection

box or folder

repository

identifier or call number

and

stable digital location.

Not every source will contain every element.

The objective is to provide enough information to identify the item reliably.

8. New Thought Organizational Archives

Specialized New Thought archives are particularly important to this project.

Collections maintained by organizations such as Unity and the International New Thought Alliance preserve substantial historical material related to the movement.

These collections may include:

correspondence;
periodicals;
photographs;
pamphlets;
manuscripts;
organizational records;
audiovisual materials;
artifacts;
and unpublished documents.

When citing these collections, we distinguish between the archival item itself and any modern interpretive description supplied by the organization.

A historical letter preserved in an institutional archive remains a primary source.

A modern exhibit explaining that letter is a later interpretive source.

Both may be cited, but they should not be confused.

9. Citation Proximity

Where practical, citations should appear close to the claim they support.

Readers should not have to guess which reference supports which statement.

This is particularly important for:

direct quotations;
disputed facts;
specific dates;
biographical details;
teacher-student relationships;
claims of influence;
medical or healing accounts;
statistics;
controversial claims;
and unusual historical assertions.

A general bibliography at the end of an article is useful, but it does not always replace claim-level citations.

10. Citation Density

Not every sentence requires a citation.

Commonly established contextual information may sometimes be supported by citations covering a paragraph or section.

However, citation density should increase when information becomes:

specific

unusual

disputed

consequential

difficult for readers to verify independently.

An article should not become visually unreadable because every ordinary sentence contains several references.

At the same time, readability should never be used as an excuse to leave important historical claims unsupported.

11. Direct Quotations

Direct quotations require attribution.

Whenever practical, a quotation should identify:

speaker or author;
source;
publication or document;
date;
page or location;
and repository or digital source when relevant.

We prefer quotations that can be traced to an identifiable primary source.

Quotation websites, social-media graphics, unsourced inspirational pages, and repeated online attributions are not sufficient evidence by themselves.

12. Famous Quotations Require Extra Verification

Historical religious figures frequently accumulate quotations they never said.

New Thought figures are no exception.

A quotation appearing on hundreds of websites may still originate from one modern misattribution.

Before publishing an important quotation, we attempt to locate it in:

the person’s published works;
correspondence;
transcripts;
sermons;
periodicals;
archival documents;
or reliable scholarly sources.

If the quotation cannot be verified, we may:

omit it,

identify it as commonly attributed,

state that the original source has not been located.

We do not convert repetition into evidence.

13. Quoting Historical Language

Historical sources sometimes use terminology that is outdated, unfamiliar, offensive, or understood differently today.

When such language is historically necessary, quotations should preserve the original wording accurately while providing context when appropriate.

We do not silently modernize a direct quotation in ways that change its meaning.

Spelling or typographical irregularities may occasionally be clarified, but substantial changes should be disclosed.

14. Books

A book citation should include enough information to identify the edition used.

Useful elements include:

Author

Title

Edition, when relevant

Publisher

Publication year

Page number

Stable digital copy or repository, when available

Edition information matters because historical works may have been revised.

A statement appearing in a later edition should not automatically be attributed to the original edition without verification.

15. Historical Periodicals

New Thought history is particularly rich in magazines and journals.

Periodical citations should ideally include:

author, if known

article title

periodical title

volume and issue, when available

publication date

page number

archive or digital repository.

Advertisements, editorials, letters to editors, news items, and doctrinal articles should be identified according to their actual form.

An advertisement proves that something was advertised.

It does not automatically prove that every promotional claim in the advertisement was true.

16. Historical Newspapers

Newspapers may be cited for:

lectures;
conventions;
obituaries;
advertisements;
public controversies;
organizational activities;
legal proceedings;
and contemporary reactions.

Whenever practical, newspaper citations should include:

article title

newspaper

place of publication when needed

date

page

and

archive or stable digital location.

Unsigned newspaper stories should not be assigned an author unless the source itself provides one.

17. Letters and Manuscripts

For letters and manuscripts, we aim to record as much provenance as the repository provides.

A useful citation may contain:

Author to Recipient

Date

Document type

Collection

Repository

Box/folder or identifier

Digital location, when available.

For example, the important point is not merely that a quotation came from “a letter.”

Readers should ideally be able to determine which letter and where it survives.

18. Photographs and Images

Images can also function as historical sources.

Image attribution should include, when known:

creator or photographer;
subject;
approximate or exact date;
collection;
repository;
identifier;
and rights or licensing information.

A modern caption attached to an old photograph is not necessarily contemporary evidence.

Where identification is uncertain, the caption should not imply certainty.

19. Websites

Web pages may be cited when they provide relevant information not better represented by another source.

Preference is given to:

universities;
libraries;
archives;
museums;
scholarly organizations;
government institutions;
and official organizational websites.

A web citation may include:

author

page title

website or organization

publication or revision date

URL

and, where useful,

access date.

Because web content can change, publication and update dates should be recorded when available.

20. Stable Links and Persistent Identifiers

Whenever practical, we prefer durable references such as:

DOIs

permalinks

archival identifiers

catalog records

persistent URLs

stable repository pages.

A stable item record is generally preferable to a temporary search-results URL.

This improves the likelihood that future readers will still be able to locate the source.

21. Link Rot

Websites change and links disappear.

A broken external link does not necessarily invalidate the citation if the bibliographic information still identifies the underlying source.

When maintaining articles, we may replace broken links with:

updated repository links;
archived versions;
stable catalog records;
or alternative legitimate copies.

We do not silently change the underlying source simply because its original URL stopped working.

22. Digitized Books

Digitized historical books may be accessed through libraries and reputable repositories.

When possible, citations should identify the historical book itself, not merely the website displaying it.

For example, the source is fundamentally:

Horatio W. Dresser, A History of the New Thought Movement (1919)

rather than simply:

a page on a digital-book website.

The repository can then be included to help readers access the specific copy used.

23. OCR and Searchable Text

Optical character recognition makes old books and newspapers searchable.

It also makes mistakes.

OCR may misread:

names;
punctuation;
dates;
page headings;
columns;
and entire words.

For exact quotations or consequential details, we prefer to verify OCR-derived text against the image of the original page whenever practical.

The scan is the source.

OCR is an aid for finding it.

24. Citations for Disputed Claims

Disputed historical questions require stronger citation practices.

If credible sources disagree about a claim, we may cite multiple perspectives.

For example:

“Dresser interpreted Quimby as foundational to New Thought, while later scholarship has placed greater emphasis on a wider network of nineteenth-century influences.”

Such a statement should make it possible for readers to identify the sources representing those interpretations.

We do not cite one side while describing the disagreement as though both perspectives had been independently documented.

25. Claims About Influence

Claims of influence require particular care.

Statements such as:

“A influenced B”

should ideally be supported by evidence such as:

explicit acknowledgment;
correspondence;
documented reading;
citations;
attendance at lectures;
teacher-student relationships;
or scholarly research establishing the connection.

Similar ideas alone do not prove influence.

Where evidence is weaker, we may use more cautious wording:

“shows similarities to”

“developed within a similar intellectual environment”

“has sometimes been compared with.”

The citation should support the actual level of certainty expressed.

26. Healing and Medical Claims

Historical accounts of healing receive especially careful sourcing.

When a historical figure claimed to have experienced healing through prayer, mental treatment, affirmation, or another spiritual practice, we seek the earliest or strongest available account.

The citation should make clear whether the evidence comes from:

the individual,

a contemporary witness,

an organizational account,

a later biography,

modern scholarship.

A religious testimony is cited as testimony.

It is not cited as independent medical proof of causation.

27. Genealogical and Biographical Information

Dates of birth, death, marriage, residence, and family relationships may be checked against sources such as:

census records;
vital records;
obituaries;
directories;
gravestone records;
newspapers;
family papers;
archival biographies;
and scholarly works.

Crowdsourced genealogy pages can provide research leads but are not automatically treated as definitive evidence.

Where genealogical sources conflict, stronger documentary records are preferred.

28. Wikipedia and Similar Reference Sites

Wikipedia and other collaborative reference sites can be useful for orientation.

They may help identify:

names;
terminology;
books;
scholarly references;
archives;
or questions requiring investigation.

However, for substantive historical claims we generally prefer to cite the underlying primary, scholarly, archival, or institutional source rather than relying on Wikipedia as the final authority.

The same principle applies to other websites that summarize sources they did not originate.

Whenever practical:

follow the citation backward.

29. Search Engines Are Discovery Tools, Not Sources

Google, Bing, library search systems, AI search interfaces, and other discovery tools can help locate historical material.

A search-results page is not the historical evidence.

If a search leads to an 1897 book, we cite the book.

If it leads to a university archive, we cite the archival item.

If it leads to a scholarly article, we cite the article.

Discovery and evidence should remain separate.

30. AI Systems Are Not Historical Sources

Artificial intelligence systems may assist with research organization or discovery.

They are not cited as authorities for historical facts.

AI output can contain:

invented quotations;
incorrect dates;
nonexistent books;
fabricated citations;
conflated people;
and unsupported relationships.

If an AI system identifies a potentially useful historical fact, that information must be verified against an appropriate source before publication.

A citation generated by AI is not considered verified until the referenced source has been located and checked.

31. We Trace Repeated Claims Backward

One of the most common problems in online historical writing is citation circularity.

Website A cites Website B.

Website B copied Website C.

Website C copied an unsourced book.

Soon dozens of pages appear to support the same claim even though they all depend on one uncertain source.

Whenever practical, NewThoughtHistory.org traces important claims backward toward their earliest identifiable evidence.

Ten repetitions of one claim do not equal ten independent sources.

32. Independent Corroboration

For consequential or disputed claims, we prefer independent corroboration when it is available.

Two genuinely independent contemporary records can provide stronger evidence than several later accounts derived from the same source.

However, multiple sources should not be described as independent merely because they appear on different websites.

We consider whether the sources actually have separate evidentiary origins.

33. Source Quality Is More Important Than Source Count

An article containing fifty weak references is not necessarily better researched than an article containing ten excellent ones.

We prioritize:

relevance

provenance

authority

proximity to the historical event

independence

and

traceability.

Citation quantity should never substitute for source quality.

34. Further Reading Is Different From Evidence

Articles may contain both References and Further Reading.

They serve different purposes.

References

Sources that directly support claims made in the article.

35. Bibliographies

Major pillar articles may include selected bibliographies.

These can be organized into categories such as:

Primary Sources

Books

Scholarly Articles

Archives

Historical Periodicals

Digital Collections

and

Further Reading.

A bibliography should prioritize usefulness rather than attempting to list every publication ever produced on the subject.

36. Citation Style

NewThoughtHistory.org prioritizes clarity, consistency, and traceability over rigid adherence to a single academic style in every context.

For formal historical references, our citation structure generally follows conventions familiar from humanities citation systems, particularly Chicago-style historical citation.

However, web presentation may be simplified for readability.

The essential requirement is that enough information is provided for a reader to identify and locate the source.

37. Recommended Citation Elements

Depending on the source type, citations should preserve as many relevant elements as practical.

Book

Author. Title. Publisher, year, page.

Journal Article

Author. “Article Title.” Journal, volume, issue, year, pages.

Newspaper

Author, if known. “Article Title.” Newspaper, date, page.

Letter

Author to recipient, date. Collection, repository, identifier.

Archival Document

Creator. Document title or description, date. Collection, box/folder, repository.

Website

Author or organization. “Page Title.” Website, publication/update date. Access information.

Photograph

Photographer or creator. Title/description, date. Collection, repository, identifier.

Actual formatting may vary according to the information available.

38. Copyright and Citation Are Different Issues

Citing a source does not automatically grant permission to reproduce it.

This distinction is important.

A copyrighted photograph can be properly cited while still requiring permission for reproduction.

Likewise, attributing a long passage does not automatically make unrestricted copying permissible.

NewThoughtHistory.org therefore treats:

citation

copyright

licensing

and

permission

as related but separate questions.

When reproducing protected materials, applicable copyright law, licensing terms, repository restrictions, and permissions should be considered.

39. Public Domain Material

Many early New Thought works are old enough that particular editions may be in the public domain in relevant jurisdictions.

However, we do not assume that every modern reproduction, photograph, transcription, introduction, annotation, or edition shares the same rights status as the underlying historical work.

Rights information should be checked for the specific item being used.

A public-domain nineteenth-century text can coexist with a copyrighted modern edition or digital presentation.

40. Image Credits

Historical images should receive appropriate attribution whenever source information is available.

An image credit may identify:

creator

title or description

date

collection

repository

and

rights status or license.

Where an image has been cropped, restored, colorized, or otherwise materially altered, that fact should be disclosed when the alteration could affect historical interpretation.

41. Corrections to Citations

Citation errors are treated as factual errors.

These can include:

incorrect author names;
wrong publication dates;
incorrect page numbers;
links pointing to the wrong source;
quotations attributed to the wrong person;
wrong archival identifiers;
or references that do not support the accompanying claim.

When such errors are identified, we aim to correct them.

Substantial citation corrections may be noted under our Corrections Policy when appropriate.

42. Reader-Submitted Sources

Readers are welcome to suggest:

archival records;
books;
photographs;
letters;
newspapers;
family papers;
organizational records;
corrections;
and other historical evidence.

A submitted source is evaluated according to the same standards as any other evidence.

We may ask:

Where did the document come from?

Who created it?

When was it created?

Can its provenance be verified?

Does an archive or library hold another copy?

Does independent evidence support its identification?

Submission does not guarantee publication.

43. Private Collections

Privately held historical materials can sometimes contain unique evidence.

When using such material, we seek sufficient provenance to describe it responsibly.

Where appropriate, a citation may state:

Private collection

along with additional identifying information permitted by the owner.

We avoid publishing sensitive personal information unnecessarily and respect legitimate restrictions placed on private archival material.

44. Anonymous and Unidentified Sources

Anonymous sources are rarely appropriate for establishing ordinary historical facts when documentary sources should be available.

An unidentified claim cannot normally substitute for verifiable historical evidence.

However, anonymous historical documents themselves may still be legitimate primary sources.

For example, an unsigned newspaper article from 1905 can be cited as an unsigned contemporary newspaper source.

The distinction is between:

an identifiable anonymous historical document

and

an unverifiable modern assertion from an unknown person.

45. What We Avoid

NewThoughtHistory.org generally avoids relying on the following as final evidence for substantive historical claims:

unsourced quotation websites;
anonymous blogs;
AI-generated answers;
social-media graphics;
copied biographies without references;
SEO pages that merely rewrite other pages;
unattributed images;
forums used as factual authority;
automatically generated genealogy profiles without documentary support;
and websites that provide no way to determine where their information originated.

Such resources may occasionally provide research leads.

They are not substitutes for evidence.

46. Our Citation Standard

Before publishing an important historical claim, we aim to answer:

What source supports this statement?

Is that source appropriate for this type of claim?

Can the reader identify or locate it?

Is it primary, secondary, institutional, or interpretive?

Does the citation actually support the wording used?

Are there credible sources that materially disagree?

Have we represented the degree of certainty accurately?

If these questions cannot yet be answered, the claim may need additional research, qualification, or removal.

Transparency Is Part of Historical Research

New Thought history survives because people preserved evidence.

Writers preserved ideas in books.

Editors preserved debates in periodicals.

Organizations preserved records.

Families preserved letters.

Libraries preserved publications.

Archives preserved collections.

Modern digitization has made an increasing portion of that evidence available to researchers around the world.

NewThoughtHistory.org builds upon that work.

Our responsibility is not merely to repeat what previous websites have said.

It is to show readers where important information comes from, distinguish historical evidence from later interpretation, and provide a path back to the underlying record whenever possible.

A citation should ultimately allow a reader to say:

“I can see why this statement was made, and I know where to investigate it further.”

That is the standard we aim to maintain throughout NewThoughtHistory.org.
