I’ve posted a listing of bibliographic data for articles in Mother Earth—in “raw” form, as complete as I have been able to make it, given the state of the card catalog data I was working with and the digital files I have been able to double-check that data against. As I mentioned when the data was all entered into the Libertarian Labyrinth wiki archive, this is a project which I would love to pursue—and not just with Mother Earth—assuming people see this sort of work as useful.
I’ll update the listings as I can verify and complete them.
