Heinz-Jürgen Ehrig, a German Science Fiction fan, has collected about 130.000 Science Fiction books, magazines, fanzines, etc. Since his death in 2003, his widow, the SciFi author Marianne Sydow has spend gazillions of hours cataloguing his collection and is now publishing the bibliographical data on a monthly basis in a paperback + CD outfit for a small fee. Unfortunately she finds it hard to get any subscribers, which is a shame really. It would be a shame if this project dies.
