In most European Union countries, these editions (except new original material) are generally protected for no more than 25 years from publication (30 years in Poland).
In Canada, new editions/re-engravings of public domain works (when not including new original material) should be in the public domain due to failing to meet the threshold of originality. This edition was published by Bärenreiter in Germany over 25 years ago and is in the public domain in its country of origin. Any commentary or critical apparatus, if protected by copyright, should not be included in the scan(s) available here.
