I like that for my cataloging class I have to discuss whether an antelope could be a considered a "document". Here is an example of one of my esteemed classmates responses:
"Each one of you clearly states your position on the Antelope, but I find it hard to see the actual Antelope as a document. One unclear point that stands out to me is the fact that the Antelope is living in a controlled environment, so how can a study be true to life. The documentation is the document not the Antelope (which someone on the discussion board stated). But I am trying to step outside the paper context into the new world of digital - someone asked how can you retrieve the Antelope. Retrieval of the Antelope could be live digital stream where the Antelope is viewed in its daily habitat. For example an art student decides to draw an Antelope, they retrieve the live broadcast where they observe the animal..."
This is all stemming from an article by Suzanne Briet* in which she posits that an antelope in a zoo (versus in the wild) becomes a document, implying that a "document" is anything that is perceived as a document, or that bears traces of human activity. From her article also comes this thought-provoking little table:
