Now available as a PDF for the first time, the German Lovecrafter Nr. 3, a “50 years of Lovecraft in Germany” special-issue. It has some in-depth and well-researched articles, by the sound of it. Obviously you’d need to translate, but there’s no indication that the PDFs have their text locked. In which case you could probably auto-translate.

Several other early issues are also now available this way, and I imagine that the following issue had some responses to the previous year’s ‘Lovecraft in Germany’ information.
