A well-regarded discussion of principles for doing research impact analysis. See additional articles linked at the bottom of its page.
To what extent does the Leiden manifesto also apply to altmetrics?
A discussion of the manifesto against the background of research into altmetrics. It discusses how the Leiden Manifesto is relevant to altmetrics, comparing the ten principles against the background of the knowledge about and the research into altmetrics.
Choose your metrics wisely
The Metrics Toolkit is a resource for researchers and evaluators that provides guidance for demonstrating and evaluating claims of research impact. With the Toolkit you can quickly understand what a metric means, how it is calculated, and if it’s good match for your impact question.
Scholarly Author’s Publication Assessment Checklist
This resource can help scholarly authors to highlight their accomplishments and demonstrate the impact of their research. It can also assist them approach post-publication strategies and publication management, manage and promote online scholarly profiles, evaluate research impact metrics, and demonstrate qualitative measures of research impact.
A collaboration with several research-intensive universities to "agree on methodologies that are robustly and clearly defined, so that the metrics they describe enable the confident comparison of apples with apples."
A “basket of metrics”—the best support for understanding journal merit
This article discusses the importance of looking at different metrics when assessing impact.
Nature Special Issue: Impact
This special issue from Nature News has several good articles about research impact.
Metrics use in universities
Bibliometrics White Paper
From the University of Waterloo (Ontario, Canada), this white paper provides a useful discussion about appropriate and inappropriate uses for metrics.
Research Excellence Framework (REF) Impact Case Studies
This site lists research impact case studies of the universities in the United Kingdom. The case studies outline changes and benefits to the UK economy, society, culture, public policy and services, health, the environment and quality of life and impacts in these sectors beyond the UK. They are an excellent resource for understanding how to demonstrate impact in academia and on the public; while citation counts to individual publications are listed, the case studies also report on details of the impact and sources to corroborate the impact.
The Use of Altmetrics in Promotion and Tenure
Provides ideas and reasoning behind using altmetrics for providing evidence of research impact for academic career advancement.
Altmetrics: A Manifesto
Written not long after the term "altmetrics" was coined by Jason Priem, the manifesto calls on the academic community to consider a more diverse and robust set of impact metrics when assessing research impact. It discusses how altmetrics are complementary to traditional, citation-based metrics rather than a replacement of them.
