Altmetrics is the study and use of non-traditional scholarly impact measures that are based on activity in web-based environments. As scholarship increasingly moves online, these metrics track associated interactions and activity to generate fine-grained data, allowing researchers and policy makers to create a higher resolution picture of the reach and impact of academic research.

Altmetrics research seeks to build and track a rich, holistic image of impact on diverse audiences (general public as well as scholars) and monitors diverse types of engagement with scholarship, including viewership, discussion, bookmarking, and recommendation, along with traditional citation.

The PLOS ONE Altmetrics Collection gathers an emerging body of research to seed further study and use of altmetrics. As an ever-growing collection, it aims to continually cover a range of subjects including statistical analysis of altmetrics data sources; metric validation, and identification of biases in measurements; validation of models of scientific discovery/recommendation based on altmetrics; qualitative research describing the scholarly use of online tools and environments; empirically-supported theory guiding altmetrics' uses; and other research relating to scholarly impact in online tools and environments. The Collection is open to all authors who wish to submit research in these areas.

Articles are presented in order of publication date and new articles will be added to the Collection as they are published. Further information on altmetrics can be found at
