retro.seals.ch is ETH-Bibliothek's platform for retrodigitized Swiss journals from the fields of science and culture. Meanwhile, more than 3.5 million digitalized pages are made available on the platform. We are pleased that the portal has added all issues of our journal FERRUM and its previous journal NACHRICHTEN AUS DER EISENBIBLIOTHEK to its range. All volumes are accessible free of charge and can be searched using full text, title, or author. Thus, issues that have been out of print for years are available again in a user–friendly way and in high quality. You can download all articles directly from retro.seals.ch as PDF files for free. We thank the ETH–Bibliothek for the smooth cooperation and the successful implementation!
