The numerical value reflecting the average number of citations received in a particular year by articles published in a journal during the two preceding years is a key metric for assessing its relative importance within its field. For example, a journal with a high value indicates that its published research is frequently cited, suggesting a significant influence on the scientific community. This value is widely used to compare different journals within the same subject category.
This metric is crucial for researchers when selecting journals to submit their work, as publication in a high-value journal can enhance the visibility and impact of their research. It also informs library collection development decisions and funding agencies’ evaluation of research outcomes. Its historical context lies in the increasing need to quantify the impact of scientific publications, evolving from simple citation counts to more sophisticated measures.
