ResearcherID is an author profile generated from Web of Science data and connected to that platform. While Dalhousie Libraries no longer subscribe to Web of Science, it is still possible for authors to register for a ResearcherID profile.
Profiles are viewable to anyone, there is no subscription required. For that reason, potential employers, collaborators, or peer reviewers may search for your profile, so it's not a bad idea to register for and claim your profile.
