The Editorial Board is inviting submissions of papers to be considered for publication in the fifth issue of the Journal of Historical Network Research, which will be published in spring 2021. We welcome proposals for papers centred on historical networks of any period of the recorded human past, from Bronze Age civilisation to contemporary history. Given the current extraordinary circumstances amid the global CoViD-19 pandemic, we particularly welcome papers that deal with historical pandemics from a network perspective. n order to foster reproducibility and transparency in historical network research, we encourage authors to provide their code and data sets in addition to the manuscripts for publication. We also encourage expressions of interest for book reviews on relevant recent literature and articles, which introduce and discuss relevant and innovative digital tools for network research, or interesting new databases and data sources.
