I was mistaken about Dirk Couprie's age, when I posted earlier. For some reason I had gotten the idea that he was an under-40 scholar. He was born in 1940!
When I posted earlier I did not have a working link to his article on Anaximander in the Internet Encyclopedia of Philosophy. I will hunt up one.
The regular IEP site is temporarily not responding.
I think Couprie's IEP article on Anaximander is quite helpful. He has also written a book, with two other historians of science, called "Anaximander in Context".
He also has a bibliography on Anaximander. Lengthy interesting list of writings.
From the looks of it, the field of Anaximander Studies is expanding
