 The SF MoMA is in possession of the original of Kalpakjian’s work, Corridor; they control access to the video imagery. At present, the work is not available to be viewed: it cannot be viewed on-line as part of a digital archive or collection, nor is it currently on view in the physical space of the museum. The image sequence comprising the work could be multiply instantiated and widely distributed, but in fact it is not. Similarly with Arcangel &amp; Davis’s work, Landscape Study #4: described as an installation, it is to be exhibited in a physical gallery alongside an arrangement of printed stills, with a television connected to a Nintendo Entertainment System. Again, the image sequence displayed on the television could be multiply instantiated and widely distributed, but it is not. Clips and copies of the landscape imagery are available on-line, but these are not taken to instantiate parts of the work itself. By contrast, works of net art are instantiated whenever they are accessed by someone on-line.
