This essay examines the ways in which authorship is considered a collaborative endeavour in the infosphere and the impact this is having on the ways that information is valued. It does this by looking at: the history of collaborative authorship; the modern figure of the author; contemporary collaborative authorship, and; by theorising on issues of trust and provenance; the difference between, and types of, online and print authorship; what role the Knowledge Economy plays in these discourses; and societal power dynamics in relation to who gets to decide the value of any given information.
