English: "Articles published between 1923 and 1977 without a copyright notice. For this time frame, if there wasn't a copyright notice in the newspaper, it's in the public domain. But you need to make sure there really wasn't a notice. That means looking carefully at copies of the entire newspaper for at least a few dates at regular intervals during the period from which you want to use articles to see whether there is a copyright notice anywhere in the newspaper."[1]
