Q. Is there a way to search articles to access their Altmetric score?

There is a free Altmetric tool that is available to help us identify these metrics on a specific article.

One option is to the author's record within Harvard Profiles

Within some of the author's list of publications you will find Altmetric information, including a link to the specific data within the Altmetric site.

Alternatively you could download the Altmetric Bookmarklet, and that too allows quick access to a specific publication's Altmetric data:
