Despite its failings, peer review remains a fundamental component of science editing and publishing. A recent article in Clinical Chemistry article looked at ways of recruiting and keeping peer reviewers. The journal's deputy editor, Thomas Annesley, explores the seven most common reasons (excuses) given by potential peer reviewers when declining an invitation. These range from “I have too little experience to be a good reviewer” to “I need to understand the entire study to serve as a peer reviewer”, and Annesley provides a counter-argument for each. Another recent article, in Learned Publishing [requires subscription], proposes the development of a reviewer effectiveness index.
