3. The book The High Cost of Death, mentioned in the article, was coauthored but only one name appeared on the book cover to increase sales. What are your thoughts on this? [via Jen]

I think this suggests something about the way in which we view collaborative works, especially writing. For academic works, it seems ok (the quiz the book cites shows this). But even in music, we prefer one band name over a list of people, and in movies one main name to associate with it. For some reason or another, it is simply more marketable to have one name. Perhaps we have the idea that two people means it is not as 'good' of a work - they each had to put in less effort - or that there will be something disjointed about it.
As the chapter suggests, the concept of authorship is steadily changing, though. With the new media that are arising within the realm of published works, that often rely much more on collaboration, perhaps multiple citations on pop culture works will become more commonplace. Maybe we will go against Foucault's individualism.
