I have a set of the two 'blue book' official BMW Workshop manuals for an e9. These are essentially like new, as I did not use them, and there are no markings, etc. on the pages. For sale at $325 plus shipping cost. They are in English. (I sold my last of four e9's about 3 years ago).
Many of the pages have printing or publications dates on them, in looking at quite a few, I find the latest printing date is 1/76, so they include even the latest models.
