Today's word is citation farm, from Lorcan Dempsey's blog, on 20 August, but I just came across it. Lorcan was responding to discussion about why he posted to a blog, rather than publishing in the library literature - "a very specific set of journals and organizations", he suggests. "The literature is a citation farm for those involved in formal research activity, and in the US, a necessary career convenience for those librarians who work within the tenure system."
Interestingly, the expression has not been taken up to a significant level, although there is a good post from Librarian In Black on how to choose between making your most sparkling thoughts into a blog post and a journal article. Yet the phenomenon - essentially, the separation of the communication purpose of writing from its role in achieving academic recognition - is pretty widely acknowledged.
