Various disciplines define primary sources in different ways. In general, primary sources contain original information that has not been interpreted or mediated by others. Primary sources document an issue, event or time period from the standpoint of a participant or direct observer, as opposed to a scholar or commentator writing about the issue or event. These materials have been created during the event, or they were created at a later date by participants or eye-witnesses. Depending on your topic or field of study, primary sources may also include other works that were produced during the time period. Primary sources will be helpful as you conduct your research, because they provide first-hand testimony and evidence about your topic.
Primary sources are produced by participants or direct observers of an issue, event or time period. These sources may be recorded during the event or later on, by a participant reflecting upon the event.
Some examples of primary sources include:
In some cases, it will be difficult to obtain the original source, so you may have to rely on copies (photocopies, microfilm, digital copies)
There are different search strategies to find primary sources, depending on what material you are looking for and where you are trying to locate the source
