Chapter 30 focuses on serving as a reviewer for others’ work. While there is a lot of contempt for this in the academic community as free labor benefiting publishers, we frame the process of reviewing as paying it forward, that is, every traditional academic publication one has is thanks to the multiple reviewers that were involved in the process and willing to serve the field. With this mindset, we explain how to volunteer to become a reviewer, being a compassionate reviewer (as we have all been burnt before by unkind – to say the least – comments), best practices in serving as a reviewer, and the expectations of the multiple parties involved in the process such as the reviewers, editors, and authors.
