For decades, scholars - and those who evaluate them - had a limited set of metrics to measure the impact of their work. As scholarship has moved into the digital realm, new opportunities to track its reach and utility have arisen.
Altmetrics, or “alternative metrics,” is a group of new methods for measuring the use and importance of scholarly research, particularly in the sciences. As opposed to more traditional bibliometrics (such as Journal Impact Factor), altmetrics provide article-level data and take into account new electronic interactions and usage, such as number of page views and downloads from a publisher's site, repository views, or discussions generated in online venues such as Twitter or blogs. While altmetrics are meant to supplement and not replace traditional metrics, many believe that article-level metrics help provide a more realistic reflection of the impact of a scholar's work.
