This commemorative publication celebrates 150 years of TU Graz Library and Archives, from its beginnings in 1875 to current developments. It traces the eventful history of this institution, reflects on the present and the future and honours all those who have shaped the library and archive. Specialist articles are dedicated to topics such as library building, teaching library, open access, digitisation, archive and research data management. An AI-generated text looks at future prospects, while a concluding essay praises the printed book. In addition, interviews with former employees provide personal insights into the transformation of library and archival work over the past decades. The result is a polyphonic work about tradition, transformation and the future of TU Graz Library and Archives and beyond in the academic library and archive sector.
