Yesterday I was present on the little Cologne workshop on digitization projects made by German libraries. I gave a talk on the results of such efforts. You can read my very critical paper in German here. At the end of my text I emphasized the importance of open access for heritage collections. Mr. Schoepflin (Library of the Max Planck Institut for the History of Science Berlin) presenting the project ARCHIMEDES (with some nice technical features) also did so.
