Attached are the latest batch of recent doctoral dissertations harvested from the issues 78-10 A and B of Dissertation Abstracts related to your subject area. ProQuest has altered how they put out their individual issues. No longer do they correlate to one month, so the dating is more random. Thus titles will range from 2018 – yes they have some 2018 dates – back into the early 1900s.
There is one additional aspect to point out about this latest batch of dissertations. ProQuest has begun adding numerous titles from many universities world-wide dating back into the early 1900s. Not all these earlier titles come with abstracts but should be available for down loading entire copies on line.
You may find some duplicate citations – the ProQuest database is including over 30% duplicate titles, sometimes in multiple months. I try and catch these duplicates but I am sure you will find that I missed some.
