A journal exists on the goodwill and expertise of its reviewer corps. Our Editors rely on high-quality, constructive, and timely reviews from the more than 4000 reviewers in our database to ensure the excellence of papers that appear in ES&T. We realize that reviewing is a time-consuming job with no tangible reward. In recognition of this, and in or-der to express our gratitude to some of our best reviewers, ES&T established an annual “Excellence in Review” award in 2003. Once again, I asked our Editors to nominate reviewers who have consistently provided both scholarly and timely reviews. We salute all of the individuals below.
