I have noticed people make free use of the Message ID in
referring to previous messages. For example, in an E-mail
reply to my recent test message here, someone wrote
In article <564@dftsrv.gsfc.nasa.gov> you write:
=>Could someone from outside Goddard Space Flight Center
Suppose I wanted to read the original message <564@dftsrv.....
There doesn't seem to be a way to fetch it directly using
this ID. Am I right in supposing that I would just have to do
a pattern search for its earliest occurence in the newsgroup?merlyn@iwarp.intel.com (Randal Schwartz) (11/30/89)

In Gnews, I just point somewhere near the message-ID in the text, and hit "@". RN would take something like "?Message-ID: <564@....>?hr" at the correct prompt.

This is a quick late-night "10-minute hack" to look up message IDs.
It works on my system, it may need a little work on yours. It's
faster than searching in rn, and will work even if the referenced
article was in a different newsgroup, and redirected followups.
(It has to be executed on the machine that keeps the history, so
it's not really useful if you are using client NFS or NNTP).

Note that C News has "newshist" in $NEWSBIN/maint. It will even work
over NFS mounted file systems (how come your's doesn't?):

Note that NNTP already has a mechanism for directly accessing articles
by Message-ID. GNUS has a couple of features which take advantage of
this; I don't know whether other NNTP readers are similarly equipped.

C News can't claim any superiority here, it just needs more debugging tools. :-) Given that I have NNTP, I'd rather use that than have to know how history is actually maintained. -=EPS=-
