Unfortunately, the editors were forced to close the access to the JFM database for security reasons. The database, last updated 2007, contained information on mathematical literature for the years 1868-1942 from the Jahrbuch über die Fortschritte der Mathematik, generated in the ERAM project (1998-2005) funded by DFG. However, the data will continue to be freely accessible via zbMATH Open, along with the additions since 2007 like the author database, reference data, and interlinking with later literature. Web pages about the ERAM project will continue to be maintained at https://www.emis.de/projects/jahrbuch-project/index.html.
