Susan Keith, a former newspaper copy editor who now teaches journalism at Rutgers University in New Jersey, is conducting a research project into "the ongoing evolution of newspaper sub editing/copy editing jobs in the English-speaking world".
However Keith appears to be having some difficulty finding subs in the UK, Ireland and South Africa to interview. If you're a current or former newspaper sub in one of these countries, please consider helping her.
Here's a description of the research project, and Susan Keith's contact details.
Keith's search for subs has already been mentioned on John McIntyre's blog You Don't Say, but I thought it bore repeating. And thanks to R Mason for bringing it to my attention.
