This document discusses the impact agenda in history and issues with altmetrics. It notes that historians define impact as partnerships with museums, commentary opportunities, documentaries, online exhibits, work with schools and heritage sectors, policy consultancy, and popular books. However, altmetrics are far lower for history articles and do not fully capture traditional impact. Altmetrics also overrepresent author involvement and underrepresent monographs. The document argues that good impact should be purposeful through citation, word-of-mouth, curation, and helping to share research. Impact includes academic allusions, appearances in media, influence on heritage and public history, and Wikipedia citations. Qualitative assessment is important over just statistics.
