What is a Primary Source?
Though definitions vary depending on the discipline in which you are working, a primary source is essentially any record or artifact from a given era that provides original documentary evidence of the time. It is like a snapshot of a given experience, taken by someone who was there. Secondary sources, such as books or articles, often draw heavily from primary sources, such as letters, diaries, or interviews, to make representations or interpretations of a period under study.
What Are Some Examples of Primary Sources?
A few examples of primary sources include:
- government documents
- newspaper and magazine articles (from the time period under study)
How Do I Find Primary Sources in an Archive?
The Society of American Archivists defines an archives as: Materials created or received by a person, family, or organization, in the conduct of their affairs and preserved because of their enduring value. Archives can also refer to the division within an organization responsible for maintaining the organization's records of enduring value, or a building or institution that houses such records.
To find materials in an archives, researchers rely on Finding Aids. A finding aid is like a table of contents to an entire archival collection, providing information on the history of the materials and their current organization. For instance, the finding aid to the Emily Dickinson Collection at Amherst College describes how the manuscripts moved from Dickinson's home to our Archives, as well as how they are currently organized in boxes and folders for easy access.
To identify primary sources held in the archives of the Five Colleges, use the Five College Archives & Manuscripts database. Bear in mind, that this database searches the text of the finding aids, not the contents of the collections themselves. A finding aid may only tell you that a certain person or topic is included in an archival collection, not detailed information describing individual letters or documents and their specific contents.
To find archival materials beyond the Five Colleges, search ArchiveGrid. ArchiveGrid is a new system that enables you to search finding aids and other catalog information from hundreds of collections across the US and around the world. When searching for a particular person, it is often useful to put their name in quotation marks (e.g. "David Foster Wallace"). In addition to finidng aids, ArchiveGrid does include records for individual letters and manuscripts.
Another handy way to determine where you can find archival materials related to a particular person or topic is to check the sources listed in a biography or other secondary work on your topic. Often the acknowledgements section of a secondary resource will highlight the most significant archival collections used by the author.
How Do I Find Primary Sources in a Library Catalog?
Scholars and publishers compile collections of primary sources that can be found in library catalogs, such as the Amherst catalog, the Five Colleges catalog, or WorldCat. Examples include published manuscripts, diaries, or letters of an individual (In Lincoln's Hand: His Original Manuscripts), or sources related to a particular topic (The Nazi Concentration Camps, 1933-1939: A Documentary History).
Like every other item in the catalog, these collections are assigned standardized subject headings or subheadings, making them easier to find. To locate primary sources in a library catalog, it is best to use the "Advanced Search" feature, with keywords for your topic in the first search box, and the subject headings for the kind of source you are looking for in the second search box (make sure the two boxes are connected with the "and" dropdown, so you are searching for both concepts).
You can search for a variety of primary sources by inserting "or" between each type of source.
Once you find an item that looks appropriate, you can identify the relevant subject headings to modify your search, or click on the link to see if there are other works with the same subjects. For example, having found a relevant book in the Amherst catalog using the above search terms, you would find the following subject headings:
Clicking on the first link takes you to a list of subject headings that you can click on to find more sources:
Common sub-headings for primary sources include:
- Archival Resources
- Correspondence [note: use this if you are looking for letters]
- Notebooks, sketchbooks
- Personal narratives
- Pictorial works
For a more exhaustive list, with examples, see MIT Libraries' page on primary source subject headings. You can copy and paste the following into a search box as "Subject Keywords" [the 'or' between terms allows the catalog to search for any of the terms, not all of them]:
"archival resources" or archives or correspondence or diaries or interviews or notebooks or sketchbooks or "personal narratives" or photographs or "pictorial works" or sources or speeches
How do I Find Primary Sources in Library Databases?
The library subscribes to a variety of databases composed largely of primary sources. These will often provide ways of either searching by keyword, or browsing in ways that attempt to replicate how they would be experienced in their original format. Though not comprehensive, the following list includes many of our primary source databases.

How Do I Find Primary Sources on the Internet?
Most archives make their finding aids available online where they are searchable by search engines such as Google or Bing. When searching the internet for archival materials add the terms "Papers" or "Archives" or "Finding Aid" or "Digital Collections" to your search. For example: "David Foster Wallace" AND "Finding Aid".
Much like the bibliographies of secondary sources, Wikipedia entries often include links to archival holdings. Check the "References" or "External Links" sections of any Wikipedia page for links to archival resources or finding aids.
