This book constitutes the proceedings of the 24th International Conference on Theory and Practice of Digital Libraries, TPDL 2020, held in Lyon, France, in August 2020.*

The 14 full papers and 4 short papers presented were carefully reviewed and selected from 53 submissions. TPDL 2020 attempts to facilitate establishing connections and convergences between diverse research communities such as Digital Humanities, Information Sciences and others that could benefit from ecosystems offered by digital libraries and repositories. The papers present a wide range of the following topics: knowledge graphs and linked data; quality assurance in digital libraries; ontology design; user requirements and behavior; research data management and discovery; and digital cultural heritage.

* The conference was held virtually due to the COVID-19 pandemic.
