[EP-underground] Duplicate papers and generations of archives

Hello,

I have some questions about duplicates and generations of archives.
I can't say that I've read all of the open-access literature, and
maybe there are already answers for my questions out there.  If so,
please let me know.

So I have some scenarios where a paper could get self-archived in
two or more servers.  I'm curious about the technical ramifications
and the etiquette.

Duplicate Scenario 1:
	Let's say that a self-archive server for my scientific
	subject area gets created that anyone in my field can deposit
	into.  This goes on for a few years and more people in my
	discipline finally "get it".  They push to get their
	institution to create an open archive.  Now they want to
	set a good example, so they self-archive their papers into
	their institutional archive, but they have already self-archived
	them into the discipline archive.  There are now two servers
	with the same information.  Or does etiquette indicate that
	once you have self-archived your paper in a server, you
	don't self-archive it again in another?

Duplicate Scenario 2:
	There is a paper with a big author list.  The third author is an 
	open access advocate, and self-archives the paper in their 
	institution's archive.  Some time later, the tenth author learns 
	that his institution has an eprints server, and without knowing
	that author 3 has already self-archived the paper, author 10
	self-archives the paper at their own institution.  Again, the
	same paper is now in more than one eprints server.  Or does only
	the first author have the right to self-archive a paper?

Duplicate Scenario 3:
	I convince my institution to create a self-archiving eprints
	server, and I self-archive my work there.  Then I get a new
	job at another institution, and they also have (or I have
	pushed to have them create) an eprints server.  Do I
	re-self-archive my earlier work at the new institution's
	server?  Naturally, this would duplicate the data.

I suppose in some sense, it doesn't matter if more than one server
has the same paper self-archived, it is up to whatever OAI
data-harvester that ends up with the duplicate "copies" to decide
what to do about them.  What I'm concerned about is the ultimate
user of the data.  If someone searches for a particular article,
are they going to get ten links to ten different eprint servers for
the same paper?


I also have a question about generations of archives.  Let's say I
begin my own personal eprints server as a demonstration of concept.
With it, I convince my department to start an eprints server.  Do
I then shut down my personal server, and put all of those papers
on the departmental server?  Similarly, the department server runs
for a few years, and people know to go there for data, and then the
university as a whole decides to run an eprints server.  Does the
department then shut down their server, and put all of their data
on the university's server?  I realize that there are clever things
that can be done with redirects and URL rewriting on the server
side to just redirect all URLs requests to the departmental server
to the university's server, to cause that transition to be almost
transparent, but still I'm curious about what you think.
