The Past Speaks

I’m trying to find out how many articles there are that correspond to the JEL code D8, “Information, Knowledge, and Uncertainty.” I don’t have access to the JEL database, since it  is restricted to members of the American Economics Association. Do you know of a quick way of finding out this information? Can a kind reader help me?

I just want to get a sense of the relative size of this field. I need this information for the literature review section of a paper on environmental knowledge flows.
