Plum Print

PlumX uses the Plum Print to visualize altmetric data.

PlumX deliberately does not aggregate their altmetric data sources into a single score.

Mousing over the Plum Print symbol reveals a pop-up box with more information on where the metrics for the article you're viewing came from. 

This is what Plum Print looks like in action:

Institutional-level Data

Institutional subscriptions to PlumX are also available.

Subscribed institutions have access to customizable PlumX Dashboards which can be used to access altmetric data at the researcher, subject, journal, school/program, and institute/centre levels.

Note: The University of Waterloo does not currently subscribe to this resource.


The University of Pittsburgh's PlumX Implementation shows how PlumX Metrics can be used at the institutional level. Using PlumX Metrics, this institution is able to track the research impact of works added to their institutional repository and library published journals.

The following screenshot shows PlumX Metrics for one of the documents in the University of Pittsburgh's institutional repository. Citation, usage, captures, mentions, and social media counts are given at the top of the page, beside the article title, and broken down in detail throughout the rest of the page.
