Finding Primary Sources Online: Contents

This page lists resources for digitized historical primary sources. Resources containing books, archives/manuscripts and mixed collections are included. Databases for particular primary source types, newspapers, periodicals, personal writings, images, films, etc., are listed on their own pages in this guide. A list of primary sources types with links is given at Outline of Primary Sources for History. We have a list of digital collections, both Harvard subscription databases and free Web collections at Online Primary Source Collections for History. It is still in an early stage of development.

General resources are listed first, then the same categories of resources, where needed, are listed by region or language.

General Digital Libraries

 HathiTrust Digital Library, Internet Archive, Google Book Search offer books and periodicals digitized from numerous libraries.  Each of these three digital libraries allows searching full text over their entire collections.

HathiTrust Digital Library is a huge collection of digitized books and periodicals. Each full text item is linked to a standard library catalog record, thus providing good metadata and subject terms. Most items pre-1925 will be full text viewable.  After 1925, a much smaller number will be full text viewable.  You can search within non-full text viewable works and obtain the pages numbers where your search terms occur.   Most US, and some state, government documents will be full text viewable.

There is also a separate full text search for US government documents.

Advanced Full Text Search

In the first (Full Text) Advanced Full Text Search field, you can put terms for a full text search.  Phrases and proper names work best (exact phrase).  If you search two or more separate keywords, when you search within particular volumes, those pages containing all the keywords will sort first.

In the second search field, you can limit your full text search by:

  • Title, searching the contents of a particular work, including periodical titles
  • Author, searching the works of a particular author, including names of organizations and government entities.
  • Subject, searching the Subject terms (same Subject terms as those used in HOLLIS) for a particular topic

Internet Archive .

  • Full text for a variety of digitized print materials and archived web pages (Wayback Machine), as well as manuscripts (a few), digitized microfilm, films, audio files, TV News, and more.  Many recent books are full text viewable if you set up a free account. You can use a Google password.
  • Unlike Google and Hathitrust, IA usually offers multiple download options including e-readers.

Full Text Search Options. You can search Internet Archive for texts bearing a specified Subject term, Title, or Author (Creator). Shift from Search metadata to Search text contents.

  • subject:Calcutta AND cholera [Use lower case for subject, title, creator]
  • title:Lessons in elementary biology AND "oosperm or unicellular embryo" [note no "" after title]
    • For a periodical: title:American Machinist AND "Spring breakage has been eliminated"
  • creator:Parker, T. Jeffery AND "oosperm or unicellular embryo" [note: The correct form of the name must be used. Find this by trying out the name in Advanced Search: Creator. When you find the right name, shift from Search metadata to Search text contents ]

Much of the Internet Archive content is organized into full text searchable Collections. Thus, if you search “Civil rights” you retrieve 104,660 items which are partially organized into 178 collections (see under Media Type in the left hand column). Some of the collections are topical (Kent State Shootings) or they include issues of a particular periodical or podcast. Collections are often nested. For example:

By no means are all periodical issues and other items included in collections. In these cases periodical titles can be full text searched using the title:American Machinist AND "Spring breakage has been eliminated" method.

Periodicals in Internet Archive

Many are available full text in the Internet Archive, including numerous trade periodicals. Search: collection:(Periodicals) AND Railroads. Select Media Type: Collections

In Advanced search:

Any field: Your topic
Collection is: Periodicals

You can search full text within a particular volume, over the whole Internet Archive, or within a particular Collection. 

  • Periodicals https://archive.org/details/periodicals
  • Serials in Microfilm https://archive.org/details/sim_microfilm

Omit colons (:) and other punctuation in titles

These searches yield individual issues and whole runs.  Isolate whole runs by choosing Collections under Media Type.

Includes:

In Advanced search you can search say Description: "South Asia", and at the top left of the results page choose Media type: Collection.  When on a Collection page, you can search within by metadata or full text

The Internet Archive is so large and various that it can be difficult to navigate.  These partial lists of contents are useful:

Google Book Search offers full text of:

  • Largely, pre-1924 books and periodicals scanned from libraries,
  • Post-1924 books and periodicals digitized in libraries. Full text searchable and snippet views displayed
  • "Previews" of books submitted by publishers. Some pages are hidden.  Some, but not all, of the hidden pages are searchable.

Internet History Sourcebooks Project

World Digital Library offers primary source materials.

The Making of the Modern World offers full text searching of works on economics and business published from 1450-1914 from the Kress Collection of Business and Economics at the Baker Library, Harvard Business School and the Goldsmiths' Library of Economic Literature at the University of London Library. Includes material on commerce, finance, social conditions, politics, public health, trade and transport. A great deal of more recently acquired material in the Kress Collection is not included in The Making of the Modern World.

Is This Book Available Open Access?

There are several sources for finding free, open access, books online.

Try HathiTrust, Internet Archive, and Google Books as described above. Harvard members should be sure to log into HathiTrust to see the Covid Temporary Access material.

Internet Archive offers numerous in-copyright books for one-hour (renewable) loan.  Free registration needed.

WorldCat Open Access searches for open access material. Adjust Search in database: from WorldCat to OpenAccessContent

The Online Books Page arranges electronic texts by Library of Congress call numbers and is searchable (but not full text searchable).  Includes books not in Google Books, HathiTrust, or Internet Archive. Has many other useful features.

The Open Library, although its books reside in the Internet Archive, includes many books not findable by searching the Internet Archive directly

OAPEN: Open Access Publishing in European Networks

OpenEdition - the Directory of Open Access Books (DOAB). Good for non-US imprints

The Digital Public Library of America’s Open Bookshelf offers numerous open access books.

WorldCat (Public version) allows limiting a search to open access material. Use Advanced Search. Check Open Access. Select Format: Book if desired.

Check your local public library ebook collection. 

Finding Primary Sources on the Open Web

There is no one way to find digitized primary sources on the Internet. The following offers methods for finding online historical resources which are more focused than a simple Google search. Most find items within digital collections. A few search the full text.

In most one cannot effectively limit to archival/manuscript sources.  Specific searches usually work better than broad topical searches.  Searches for proper names often yield good results.

The Digital Public Library of America

The Digital Public Library of America offers textual, visual, and sound resources contributed by numerous libraries, archives, and museums.  Searches catalog records, not full text, and links to the items on the contributors' websites.  Contains many individual items, such as letters and photographs, from digital collections.

Advanced Google Searches

General Google searches may yield very many results, and it may take much sifting through the results in order to find relevant items. Using Google Advanced Search with specific search terms can help yield more focused results.​ Detailed instructions for searching Google Advanced Search.

Bielefeld Academic Search Engine

Bielefeld Academic Search Engine (BASE) searches metadata and some full text, from over 2000 sources of academic open access documents.  About 60% of the documents indexed are available full text.  The metadata searched is provided by the source and tagging is often inexact.  This is a vast collection of documents and has much not available elsewhere.
Use Browsing to narrow your search to subject area (e.g., Literature) or Document type (e.g., Manuscript, broadly construed).  Open Browsing and choose-Dewey Decimal (for Subject), choose major subject to see next finer level, twice.  After choosing View Records add a search term to the Subject Term or Document Type:

EROMM

EROMM: European Register of Microform and Digital Masters searches its own database of records of printed and handwritten material in digital form or on microfilm from institutions worldwide and offers web search for such material.

WorldCat (the OCLC Union Catalog)

Numerous digitized collections of primary sources have records in WorldCat.  These collections of primary sources are often swamped by ebooks on the same subject. There is no one perfect method for finding them, but the following may be tried for any topic.  Always find the proper Subject terms for your topic and search using those as well as any keywords.  Use Advanced search. Detailed instructions for searching WorldCat.

OAISTER is a subset of WorldCat for open access online academic material. It can be useful in separating digitized primary sources from the numerous ebooks in WolrldCat.  It includes digitized books and journal articles, open access publications, manuscript/archival material, photographic images, audio and visual files, data sets, and theses. It includes such a vast range of resources that digitized archival and other primary sources are lost in the abundant results if a broad topical term is used.  So it is best to use a narrow term or proper name. Thus "Act-Up" yields archival letters. It is possible to limit a search to Archival Material, but I have not found this to be useful.

Finding the Right Subscription Database

To find databases available via Harvard Library by subject, go to HOLLIS Databases, scroll down to Best Databases for… and open History, or other topic.  Refine your results set on the right.  For example, for historical resources relating to women, go to Subject Category, open Show More, open Women, Gender and Sexuality Studies.  Also look for research guides on your subject among the Harvard Library research guides (Open Guides by Subject).

Because there are so many subscription databases, and because each database often includes numerous subcollections, it is difficult to know which databases may contain the sources you want.  For example, Vietnam War and American Foreign Policy, 1960-1975 (ProQuest History Vault) includes U.S. State Department Office of the Executive Secretariat Crisis Files. Part 1, the Berlin Crisis, 1957-1963.  Detailed instructions for finding these subcollections.

Local Online Sources

Many sources digitized by local public libraries, historical societies and other institutions may be found via the Digital Public Library of America, the state/regional portals, and worldwide, via the tools listed below.  But some will not be findable. For local sources one may visit the websites of nearby institutions.

Searching Early English Books Online (EEBO), Eighteenth Century Collections Online (ECCO) and Early American Imprints.
Since spelling in early books is variable and the long s (which looks like an f) is often used, it is important to try variant spellings and the wild card feature. ECCO offers fuzzy searching in Advanced Search

Both Early English Books Online (EEBO) and Eighteenth Century Collections Online (ECCO) contain full text of most books published 1475-1800 in Great Britain and North America and books published in English anywhere.

Early English Books Online (EEBO) offers full text for works, including much ephemera and many periodicals, dated 1475-1700. Uses Library of Congress Subject Headings.

EEBO uses page images and OCR text. Although searchable by words and phrases, there are character recognition errors and full Boolean searching is not possible. Early English Books Online Text Creation Partnership has input over 25,000 works and offers corrected text and full Boolean and other search capabilities for this subset of EEBO.

Periodicals included in EEBO include corantos, newsbooks and periodicals included in the Thomason TractsPeriodicals Search guide.

Search Guide: Early English Books Online (EEBO)

Eighteenth Century Collections Online (ECCO) offers full text for English language works dated 1700-1800. Uses Library of Congress Subject Headings. Searchable by words and phrases based on the OCR text. Many 18th century American imprints are not included in ECCO because they are available in Early American Imprints (EAI) (next).

Both EEBO and ECCO are based on the English Short Title Catalog (ESTC) which has over 470,000 catalog (no full text) entries listing books, periodicals, newspapers and some ephemera printed before 1801. Works published in Britain, Ireland, British colonies, and the US are included, together with items printed elsewhere which contain significant text in English, Welsh, Irish or Gaelic. Books falsely claiming London publication are included. Items omitted from ECCO because they are available in EAI are represented in the ESTC. Reprints (reissues of original works) are not usually included in ECCO; they are fully represented in the ESTC.
