At eLife, we strongly support the improvement of research assessment, and the shift from journal-based metrics to an array of article (and other output) metrics and indicators. If and when eLife is awarded an impact factor, we will not promote this metric. Instead, we will continue to support a vision for research assessment that relies on a range of transparent evidence–qualitative as well as quantitative–about the specific impacts and outcomes of a collection of relevant research outputs. In this way, the concept of research impact can be expanded and enriched rather than reduced to a single number or a journal name.

With less (or ideally no) involvement of impact factors in research assessment, we believe that research communication will undergo substantial improvement. Journals can focus on scientific integrity and quality, and promote the values and services that they offer, supported by appropriate metrics as evidence of their performance. Authors can choose their preferred venue based on service, cost and reputation in their field. All constituencies will then benefit from a deeper understanding of the significance and influence of our collective investment in research, and ultimately a more effective system of research communication.
