Jef Delvaux, a Ph.D. student in philosophy at York University, has undertaken the project of putting together a bibliography of writings by philosophers about the COVID-19 pandemic and related issues.
The bibliography is divided into three sections: academic philosophy, written public philosophy, and non-written media. Mr. Delvaux notes that the bibliography is a work in progress, so perhaps further categorizations will be added at some point.
The bibliography is below. You can also access it directly here.
