I discovered tonight that Walter de Gruyter is digitising their books and journals and making them available online. There are calling it the de Gruyter Reference Global. I was able to download a couple of Galatians articles that I didn’t have in pdf yet. So far they only seem to have the more recent issues up. I look forward to being able to download some of the older ZNW articles on Galatians.

and a not directly related, but interesting examination of Simon Gathercoles’ work by Bruce Longenecker:
