“Primary sources are materials in a variety of formats, created at the time under study, that serve as original evidence documenting a time period, event, people, idea, or work. Primary sources can be printed materials (such as books and ephemera), manuscript/archival materials (such as diaries or ledgers), audio/visual materials (such as recordings or films), artifacts (such as clothes or personal belongings), or born-digital materials (such as emails or digital photographs). Primary sources can be found in analog, digitized, and born-digital forms.”Primary sources can be defined slightly differently, depending on the discipline. In the humanities, we mostly think of primary sources as first-hand testimonies from sources who witnessed or experienced an event firsthand. Examples for primary sources include, but are not limited to: letters, photographs, diaries, musical scores, ephemera, artistic works, first publications of discoveries, interviews, journal entries, scrapbooks.

Primary sources are not necessarily old or physical materials only. An email, a YouTube video, or an Instagram post can be considered a primary source as well.
The difference between primary and secondary sources is that primary sources are original documents or sources that were created at the time studied while secondary sources are interpretations and analysis of primary sources.
