Self-archiving of multiple versions of same article

[Atanu Garai <atanugarai.lists@gmail.com>]

Dear Colleagues

According to EPrints Self-Arhiving FAQ 
(http://www.eprints.org/openaccess/self-faq/), the author should 
deposit following copies:

"All significant stages of one's work, from the pre-refereeing 
preprint to the peer-reviewed, published postprint, to 
postpublication updates should be self-archived. The OAI tags 
keep track of all versions. (Note that the postprint need not be 
the publisher's proprietary PDF: there should always be a link to 
the publisher's official version, however, for scholarly 
purposes.)"

This allows and requires the author to self-archive many versions 
of the same writing. I am looking for survey-based research, if 
any, on the effects of this practice on scholarly communication 
vis-a-vis availability of single version of writings. Also, of 
interest would be comments on the recommendation of archiving 
multiple versions of the copy.
