Luther and the Scriptures by J.M. Reu

Here's a book I spent a lot of money on 10 years ago: Luther and the Scriptures by J.M. Reu. I just found this as a pdf, quite by accident. I don't know whose website put it up, but thank you.

In English, I don't think there's a better scholar on the construction and background of Luther's Bible than Reu. Many of his other books are available via Google and the Internet Archive, but this is the first time I've found this one.

His most extensive treatment of Luther's Bible was
Luther's German Bible: an historical presentation, together with a collection of sources,  also now available online.
