Template documentation[view] [edit] [history] [purge]Usage
This is an inline template used to flag inappropriately cited deprecated sources, which are questionable and discouraged from use.
When the template is added to a line of text in an article, the resulting clean-up tag links to Wikipedia:Reliable sources/Perennial sources.
This template categorizes its tagged articles into the maintenance category, Category:All articles with deprecated sources, which is hidden in mainspace articles by a default setting in the user preferences. A logged-in user may view this and all other hidden categories by checking Preferences → Appearance → Advanced options → 
Show hidden categories.
This template takes a compulsory parameter (which a bot will set if the editor doesn’t):
|date=date—in the format “Month Year” or “YYYY-MM-DD“, etc.
If there is no doubt at all that the source is deprecated and used inappropriately, you can use a parameter to remove the “?” from the template’s output:
|certain=yesor|certain=y
