In the landscape of cultural heritage, private archives have traditionally functioned as guarded repositories of corporate memory. As a partial response to the chronic understaffing and resource gap of smaller institutions devoted to the preservation of historical documents (King et al., 2016), the digital turn has offered an unprecedented opportunity to redefine the role of archives as places where the public actively participates in the co-creation of a social form of historical knowledge (Keane, 2017). The Archivio Storico Ricordi—the historic legacy of the Ricordi music publishing house, home to one of the most important private collections of Italian opera—has addressed this challenge by developing digital projects that place the user at the center of the archival process.

Our paper analyzes three distinct models of participatory interaction implemented by the Archive, demonstrating how digital tools can nurture generosity and shared creativity in the preservation of the musical past. The first model is a form of collaborative transcription, exemplified by the “Lettere di Casa Ricordi” project. Facing the immense task of transcribing thousands of handwritten letters, the Archive developed a workflow that allows external contributors to submit transcriptions. This initiative has successfully engaged a diverse community—ranging from musicologists to amateur enthusiasts—transforming the solitary act of reading into a collective effort of deciphering and validating historical sources. The second model explores the possibilities opened up by open ecosystem integrations, applied in the “Riviste Ricordi” project through the collaboration with the Wikimedia Foundation. Rather than building a siloed platform, the Archive chose to upload its historical periodicals to Wikisource. This strategy activates the “volunteer philologist,” engaging the vast Wikimedia community in proofreading OCR text and creating hyperlinked data. It represents a shift from institutional control to community stewardship, ensuring that the content remains open, accessible, and constantly improved by the public. The third project “Puccini Online” focuses on a model of active co-creation as a core principle of the notion of Public History. Conceived as an aggregator of key documentary sources (held by both cultural institutions and individual citizens) and as an infrastructure integrating heterogeneous digital records, the portal calls upon the global community of Puccini lovers to actively expand the archive’s boundaries. By facilitating the submission of private documents and local histories related to the composer, the portal acts as a bridge between the institutional archive and the distributed, personal memories held by the public, crowdsourcing the collective memory of Giacomo Puccini’s legacy (Noiret, 2022).

Together, these initiatives illustrate a comprehensive strategy for digital engagement. They show that successful public history in a private archive requires flexible infrastructures capable of accommodating different levels of participation—from mechanical correction to scholarly transcription and original contribution (Zhang & Dong, 2024). By presenting these cases, we aim to discuss the challenges and rewards of this participatory turn, offering a roadmap for other institutions seeking to build meaningful connections with their audiences through digital means.
