How should political scientists communicate findings that are relevant to public debate or policy in the midst of a major crisis? One option, the op-ed, allows for rapid publication and broad readership but rarely permits detailed data analysis. Another option, the refereed article, allows for rigorous and refereed research, but academic publishing timelines often mean that a year or more will pass between submission and publication. Many other alternatives, such as blogs and preprints, face the same trade-off between rapid dissemination and rigorous review. The CJPS/RCSP COVID-19 research note series was an extended experiment in providing a new publication avenue for political scientists. The goal of the series was to provide scholars with an opportunity to quickly communicate relevant research findings while still permitting rigorous data analysis and peer review. Submissions to the COVID-19 series suggest that many political scientists were eager to embrace the opportunity: in just two months, we received 95 English-language submissions. 1 Of these submissions, 24 were accepted for publication and are printed in the pages below. These notes speak not only to the diverse interests of the political science community but also to the wide-ranging effects of the pandemic itself. One theme addressed by many of the COVID-19 notes is the institutional context and consequences of the pandemic. On federalism, for example, Béland et al. (2020) describe the prospects for the pandemic to serve as a critical juncture in Canadian fiscal federalism; Hanniman (2020) also addresses this theme. Paquet and Schertzer (2020) argue that the concept of "complex intergovernmental problems" helps us understand the challenges of intergovernmental policy making on COVID-19. Parliamentary institutions also received considerable attention; McDougall (2020) describes "continuity of constitutional government," Malloy (2020) traces parliament's multiple roles and purposes, and Rayment and VandenBeukel (2020) extend Malloy's analysis with data on federal and provincial legislatures. Koop et al. (2020) provide an interesting assessment of similar issues from the perspective of individual MPs themselves. Other institutional dimensions of the pandemic are treated in De Silva's (2020) analysis of human rights commissions, Macfarlane's (2020) discussion of constitutional limits on COVID-19 policies, and Puddister and Small's (2020) comparative analysis of courts. Political behaviour is a second recurring theme. One important discussion concerns the effects of partisanship on pandemic-related behaviour and attitudes.
