The InfoVis-DL 2026 workshop — Information Visualization in Digital Libraries: Multi-modal Applications to Cultural Heritage Collections — will take place as a half-day, in-person event co-located with International Conference on Theory and Practice of Digital Libraries 2026 on 21 September 2026. The workshop will bring together researchers, practitioners, and cultural heritage professionals to discuss real-world applications, case studies, methodologies, and challenges related to information visualization in digital libraries and multi-modal cultural heritage collections.

The rapid evolution of technologies for knowledge extraction, management, and dissemination is transforming digital libraries. Advances in AI, knowledge graph representations, and data integration enable increasingly complex and multi-modal digital collections. However, these developments also introduce significant challenges in terms of usability, interpretability, scalability, and sustainability. In the context of cultural heritage collections, spanning libraries, archives, and museums, data is inherently heterogeneous, unstructured, and multi-modal. While infrastructures increasingly support FAIR data principles, linked data, and interoperability, effective user access and exploration remain limited. Information visualization plays a central role in addressing these challenges by enabling:

• Exploration of (un)structured data.

• Interpretation of complex relationships.

• Creation of multi-modal user experiences through storytelling and generative AI.

• Support for knowledge discovery and decision-making.
