Stevan Thank you for your full and illuminating reply to my query about how much material in OA archives is available as full text. I am surprised at how low you estimate the figure to be and that it is not, yet, possible to produce a definitive number.
I am wondering if the Open DOAR (Directory of Oopen Access Repositories - the 'sister project' to the Directory of Open Access Journals, DOAJ) will set strictly 'full text only' rules for inclusion in its directory? And how will it relate to the archives.eprints directory you are involved with? It gets confusing to me because there are so many lists of repositories around on the web. How does the celestial harvesting list you mention relate to the archives.eprints list (are they the same list?) or the large list kept by the University of Illinois at Urbana-Champaign (UIUC) at <http://gita.grainger.uiuc.edu/registry/>? I take the archives.eprints to be the closest to a definitive list of the OA Institutional Repositories which we are concerned with here - alhtough I notice that our 'DSpace@Cambridge' repository <http://www.lib.cam.ac.uk/dspace/index.htm> is not included. I see the distinction between OA Archives and the Open Access Initiative. Maybe this is not strictly relevant to this forum and a basic misunderstanding of the purposes of archiving, but I still cannot understand why people are archiving *just* the metadata and not the full text. It makes OA search engines like OAIster more like a any other standard bibliographic database with mostly subscription-only access. I am interested in the whole area of Open Access and keeping up with developments. This forum is excellent for that purpose. Thank you.
