standard can it be considered deprecated? Secondly, one man's obsolete is
another man's current news. When current scholarship renders a half century
of reputable, WP:ATT, etc citations obsolete, although some material from
the older literate *still* has value, how do we mark as obsolete and
deprecated older citations that are errantly being used to refute newer
scholarship?
It's not up to us to do this. If there is someplace that says that the
idea has become obsolete or deprecated, Just site the source in the same
way that you would anything else. If someone is claiming that an old
source refutes a new one the citations for the two will still show dates
of pubblication.
