General Digital Libraries

Google Book Search, HathiTrust Digital Library and Internet Archives offer books and periodicals digitized from numerous libraries.  Only out-of-copyright, generally post-1923 books are fully viewable.  Each of these three digital libraries allows searching full text over their entire collections.

Google Book Search

HathiTrust Digital Library. Each full text item is linked to a standard library catalog record, thus providing good metadata and subject terms.  Thus a full text search of the whole database can be limited by title or Subject term.  The catalog can be searched separately.  Many post-1923 out-of-copyright books, especially government documents, are full text viewable. You can search within copyright books to see what page your search term is on.

Internet Archive now offers a full text search. Put your terms (phrases or personal names, in quotation marks (""), work best) in the search box and choose Text Contents.

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.

English Language

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 Tracts. Periodicals 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.

NINES (Networked Infrastructure for Nineteenth-Century Electronic Scholarship) (1770-1920) is a searchable (full text search available) database of selected digital scholarship and of websites related to the British and American long 19th century.

Finding More Digital Libraries and Collections

General (Include open access scientific publications, etc.)

There is no one way to find digitized primary sources on the Internet. The following websites are search engines for digital collections (and thus more focused than a Google search) or lists of digital collections and other online resources. Most of the search engines do not allow limitation to digitized manuscript/archival material, and so manuscript/archival material is often swamped by printed matter and open access scientific publications. Using appropriate search keywords (e.g., papers, correspondence, EAD) is useful. Image limitation is more frequent.


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.

Within Google Advanced Search, use the “all of these words” and the “this exact word or phrase” to enter keywords for your subject, for example,

  • all these words: Botanists
  • any of these words: archives manuscripts correspondence diaries scrapbooks sources letters

Also try:

  • all these words: Botanists
  • any of these words: "digital archives" "digital collection" "online collection"

Also try:

  • all these words: botanists Hawaii
  • this exact word or phrase: “archival collections” “manuscript collections”

Also try (separately):

all these words: botanists  WITH this exact word or phrase: finding aid

all these words: botanists EAD

For any of these searches, use the “site or domain” box to search within just .edu, .org, or .gov sites.

Google Primary Sources Search

Google has created a customized search for primary sources. Use the same terminology suggested for the Google Advanced Search to customize your search. General subject or person searches without the “digital collections” etc. qualifiers will yield more results, but the results list can be a bit disconcerting by identifying items in isolation, without giving you an idea of the broader collection they are located in. As with other Google searches, there is no controlled vocabulary.

Other libraries' research guides are often useful:

In Google Advanced Search

all these words: library [your topic keywords]

any of these words: guides research resources

site or domain: .edu  [or or country domain, etc.]


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.

Search examples:

Search: African American Women Authors
Material type phrase: Updating website

African American Women Writers of the 19th Century

You may also combine your search keyword with terms indicating primary sources (Archives, Correspondence, Diaries, Interviews, Manuscripts, Notebooks, sketchbooks, etc., Personal narratives, Sources), thus

Subject terms search: marriage history
Subject terms search:sources or archives or correspondence or diaries
Material type: not ebook
Limit type to: Internet Resources

Willie Harris collection 1950s-1970s consists of photographic prints documenting social customs, religious life, weddings, organizations, and other affairs of African American men, women, and children in Baton Rouge, La. between the 1950s and 1970s.

Search: women slavery
Material type phrase: Internet resource
Limit type to: Archival Material

Yields: Virginia Norfleet circa 1900. reminiscences

The latter two searches will yield a mix of digital collections and digitized finding aids.


OAISTER is the largest search engine for online academic material. 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.

The Digital Public Library of America

The Digital Public Library of America searches online material emanating from numerous US libraries.  As in OAISTER, one cannot effectively limit to archival/manuscript sources, so broad topical searches are difficult.  Specific searches work much better.  Searches for proper names, again like OAISTER, often yield individual items (photographs, letters) within collections.

Other general sources for digital collections

British Columbia International Digital Library lists digital collections by place and subject.

OpenDOAR (Directory of Open Access Repositories) uses a very simple Google search to search its over 1650 repositories worldwide. Includes all kinds of digital material. Cannot limit to particular types of material. Does not use OAI-PMH protocol unlike several others, so gets different results.
