摘要：Academic authors and funders often want to know the “impact” of their publications, and this impact is generally judged by how and where the paper is cited in other academic works. This limited appraisal has been expanded in recent years as many are beginning to argue that nonacademic publishing venues should be included in assessing the impact of academic publications. This is an issue of particular concern with the growing emphasis on “knowledge translation” from the scientific literature to policy and practice applications 1 – 3 and to sources other than the traditional peer-reviewed and indexed venues, in other words, translation into the “gray literature” 4 .
