Philosophy of Science owes a debt of gratitude to its referees–the Associate Editors, the members of the Editorial Board, and the many other individuals who help to review submissions. The ongoing pandemic has continued to present unique pressures and challenges that make the dedication of these individuals all the more admirable. In addition, the journal transitioned this year to its new home at Cambridge University Press, which also brought additional work. In acknowledgement of their essential service, we list here the names of those individuals who have refereed papers since the April 2021 issue went to production. (If anyone who has refereed a paper for the journal has inadvertently been left off this list, we offer our sincere apologies.)
