Collection Care in Progress. Compared to artworks preserved in museums, the obsolescence of technical devices is considerably faster, and this media artworks belong to our cultural heritage. The most vulnerable works in the collection of Ludwig Museum are photographs, prints and media works. In Hungary, media art does not only mean software-based or digital art. Before the regime change in 1989, photography was the only available media. Earlier documentation of a performance is becoming artwork today, as exclusive evidence of an artistic action. In most cases, to not show an artwork simply means not allowing it to come into being at all. In a series of interviews with artists, this paper has been interested in issues which try to uncover the meaning and the context. The methodology of collecting, presenting, conserving media art are entirely new fields for professionals working in Hungarian public collections. What do we have to preserve, and what is it that truly matters? Well... These are the questions we strive to answer.
