Use this template to "tag" information or analysis that you believe is improperly or unnecessarily supported by a primary source, so that other editors can see whether this use is appropriate or replace it with a citation to a stronger, secondary source. There is no need to do so. [[Wikipedia:Identifying and using primary and secondary sources|Primary sources may be used on Wikipedia, but they need to be handled with care.]]
[[Wikipedia:Secondary does not mean independent|'''"Primary source" does not mean that the author is too closely affiliated with the subject.''']] As a general rule, primary sources include all scientific journal articles about experiments, as well as news reports and other documents dating from around the time of an event. To tag an article as lacking [[Wikipedia:Independent source|independent reliable sources]], please use the template {{tlx|third-party}} instead.
