Metrics are being used more and more as a measure of research impact and influence. Love them or hate them, metrics are part of your research track record and may be considered when you apply for jobs, grants and promotions. Confused about what they are and what they mean? The Library has produced a web site of information about metrics, rankings, and citation counts - information you can leverage to present yourself and your work in the best possible way. There is information about using open access to maximise the exposure of your work online, and hence increase the number of times it is cited.
