Here are my new findings (entry in German): http://archiv.twoday.net/stories/5374120/
There a now lots of bibliographical entries but very few fulltexts. Eprints software doesn't allow to count the number of free fulltexts in ZORA nor it is possible to filter a search to get only fulltexts. Number of fulltexts of members of the Historical Institute: 0 (of 19 entries). Number of deposits on December 5, 2008: 50 Free fulltext: 10 Registered users (Uni Zurich) only: 27 - with Request button: 3 No fulltext: 13. Klaus Graf
