Popular publications such as magazines are primary sources.
Archives preserve the documents and records of an organization and may contain unique or rare items. In general, they do not lend and have specific policies for using their facilities, making copies, etc.
"A primary source is a document, image or artifact ... created contemporaneously with the event under discussion." (Williams, Historian's Toolbox, 2nd ed., p. 56)
Primary sources are evidence from participants in or eyewitnesses to an event.
