“…We can again distinguish between data about offline and online behaviors. Trace data about offline behaviors can be extracted from (offline or online) historical archive records (e.g., Bloch et al, 2022), population register data (Van der Laan et al, 2022), newspaper archives for discourse and policy networks (Nagel and Satoh, 2019), epidemiological contact tracing data for COVID-19 contagion (Hâncean et al, 2020), Scopus or Web of Science records for coauthorship (Akbaritabar and Barbato, 2021), policy event descriptions (Pal and Spence, 2020), or national statistics for networks of flows among countries (Danchev and Porter, 2018), to name but a few options.
