One cause for articles appearing multiple times, even if the article was
originally posted only once but to multiple newsgroups, is that article
passing through a version of news software which doesn't understand
posting to multiple newsgroups.  Those versions of news - A news, older
versions of B news (pre-2.9), and possible the "notesfiles" system as
well - will treat an article posted to N newsgroups as N identical articles
posted to each of the N newsgroups.  If Usenet sites were all running news 2.10
or later, an article posted to multiple newsgroups would only appear once
and would only be stored in one file.  (Furthermore, the "References" line
would be available for all followup articles; some news systems delete this
line on incoming articles.)
