For years Dan Filler and I have talked about the benefits (and pitfalls) of putting papers on-line before publication. I am more skeptical of this than Dan, but he's won me over, more or less. There is, however, a vibrant debate -- I think especially in the humanities -- about the wisdom of putting a dissertation on-line. Here's a statement, entitled "Princeton’s Online Dissertation Submission Policy and How it Affects Humanities and Social Science Graduate Students," from Princeton humanities Ph.D. students from 2011 about this issue. The document makes for interesting reading for a bunch of reasons, including the views about what's required for tenure in the humanities, how much manuscripts are revised from dissertation to publication, and the widsom of staking out territory vs. keeping hard-won research and insights under wraps.
