Yes, the economists’ papers could be harvested (at a finer grained level and when relevant to LIS) irrespective of the broad IR - but this is not a trivial problem to solve as we found out when we wanted to harvest only certain subjects from ArXIV for example. If I’m not clear do try some of the open access aggregator services based on OAI-PMH and I think you’ll see what I mean. Also take a look at the subjects listed in DLIST - we’ve taken a lot of heat for this mix of broad and narrow subjects but there’s a bit of method to our madness as I hope time will show.

Delighted by your interest and appreciation and will look forward to more inspired musings. Thanks. A
