A primary source is any record contemporary to an event or time period. Primary sources may be written, oral, visual or physical. Some of these sources were produced with the intent of being preserved for the future. Such intentional sources include government documents, church records, autobiographies or memoirs. On the other hand, many primary sources were produced without any intent of future use. Such unintentional sources may include private correspondence not originally meant for posterity but which later are deposited in archives and libraries. Physical evidence such as buildings, clothing, tools, and landscapes may also be labeled as unintentional sources.

Primary sources are often found in archives and special collections (either separate, special libraries or special-collections sections of larger libraries). Some of these locations make parts of their collections available online.

In the simple keyword search box, you can put such words, enclosed in "quotation marks," after SU in order to specify the SUBJECT field.
