Inspired by Simon Meier-Vieracker, I track how long the peer review and production process takes for each of my publications. Journal articles are red; conference proceedings yellow; book chapters blue. Light color indicates time waiting for reviews; dark color typesetting; diamonds date of publication.
I also keep track of reviews I have performed for journals. The chart below shows how many reviews I have performed/declined for different journals, and how long they took. Negative times indicate declined review requests.
