This guide provides links to resources for bibliometric analysis, including journal ranking indices, such as impact factor (Thomson Reuters) and author impact measures, such as h-index (Hirsch, JE).
Much has been written about bibliometrics and their use in measuring impact. This guide does not attempt to compare the benefits or limitations of different metrics, or encourage or discourage the use of any particuar metric. For that type of analysis, see, for example:
