Bibliometrics can help you to make decisions about where to publish your research and how to get information about the impact of published research.
Impact factor is a metric used to assess a journal's relative impact within its field, with journals with higher impact factors deemed to be more impactful than those with lower ones. Impact Factor is based on the number of citations a journal receives within a 2 year period.
H-index is a metric used to measure a researcher's productivity (number of publications) and the impact of their work (how many times their articles have been cited).
Relative Citation Ratio (RCR) is "a field-normalized metric that shows the citation impact of one or more articles relative to the average NIH-funded paper." For more information on RCR see:
