Im Januar 2023 sind alle Publikationen mit Erscheinungsjahr 1927 auf Hathi Trust frei zugänglich (weltweit freie Publikationen hier). Für den Zugriff von hier aus ist dafür ein VPN nötig (via Newsletter Hathi Trust December 2022):
«In January, HathiTrust will once again celebrate the return of Public Domain Day. This coming year, titles published in 1927 will enter the public domain in the United States, including more than 61,000 items in the HathiTrust collection. Some of these will also be viewable globally. Global readers will also gain public domain access to 41,745 titles published in 1897, and up through 1902 if published in Canada or Australia.
Here is a sneak peek of works that will be opening in January. Your favorites might already be open thanks to the copyright review program.»
