The Institute for the History of Frankfurt (ISG) offers a comprehensive digital portal dedicated to exploring the history of Frankfurt am Main during the Nazi regime from 1933 to 1945. This platform enables users to engage with the city's past through multiple access points, including curated topic lists that guide visitors to articles and documents, city maps providing a topographical view of the era, and timelines outlining chronological events. Users can also benefit from an alphabetical index of individuals and subjects for targeted research, along with a full-text search function for efficient navigation.

The contributions featured on the portal are the result of collaboration among authors and editors from diverse institutions and organizations, aimed at delivering succinct expert insights rather than exhaustive academic analysis. The ISG actively invites user feedback to enhance the portal’s offerings.
