Altmetrics is used to refer to "alternative metrics" which measure the online impact of scholarly and creative works - generally at the article level. Altmetrics attempts to fill a gap in more traditional metrics by using a wider range of sources, such as social media, news outlets, blog posts, and citation managers, in addition to citation and download counts to determine the impact (or "attention") of scholarship.
You can find altmetrics in a variety of places, including on journal publisher sites (like Taylor & Francis and Wiley), repository sites (like PubMed Central and UNLV's institutional repository), and even some databases (like Scopus). Check out the chart below for a detailed comparison of altmetrics and traditional metrics.
Altmetric Explorer is a database that is used to track altmetrics, based on the digital object identifier (DOI) or persistent URL of a publication. The publications that it tracks include e-books, patents, policy documents, journal articles, and virtually anything with a DOI attached from known sources (such as CrossRef).
UNLV researchers have access to this database through the University Libraries databases. Create your account and login using your institutional (@unlv.edu) email address.
You can request a one-on-one or small group consultation, or a demo of this database by reaching out to Christina Miskey, Research Impact Librarian, at christina.miskey@unlv.edu.
The table below provides a quick preview of what type of information you can utilize from various sites that showcase traditional metrics or alternative metrics (or both). For more information on each metric and how to obtain it, please refer to the Bibliometrics and Altmetrics Guide.
