More than your h index

  1. 1. Tanya Williamson, Assistant Librarian MORE THAN YOUR H-INDEX?
  2. 2.  Journal articles published by an author  Citations to journal articles published by an author  An attempt to generate a quantitative representation of a scholar’s ‘output’ WHAT ARE AUTHOR BIBLIOMETRICS? The h-index: If a scholar has 20 articles which have each been cited 20 times, s/he has an h-index of 20 Times cited: Total citations to all of an author’s works Average citations per item: Total citations/Total items
  3. 3.  Universities are often looking for a quick way to evaluate performance (productivity and impact)  The h-index is easy to calculate and understand, so has gained traction  You may gain insights into your own influence  You may find potential collaborators WHY SHOULD I CARE?
  4. 4.  Google Scholar  Web of Science  Scopus  Publish or Perish: free application. Uses data from Google Scholar to calculate a wide range of author metrics, including improvements to the h-index that attempt adjust for:  Length of career  Highly cited papers  Active vs inactive researchers  Co-authorship HOW TO FIND YOUR H-INDEX (and other metrics)?
  5. 5.  Can’t be used fairly to compare across disciplines, or meaningfully in some disciplines  Name ambiguity – getting a comprehensive list is not easy  Values differ depending on the source data  No one metric can capture all ‘impacts’, or facets of ‘research performance’  Will not be favourable if your research does not result in journal articles  Early career researchers will be at a disadvantage  Citations ≠ endorsements of quality! WHAT’S WRONG WITH THE H-INDEX (and other metrics)?
  6. 6.  Consider what is the most appropriate measure for you, your discipline and the impact you were aiming to achieve  Article-level metrics: include views, downloads AND citations Emerging:  Altmetrics, such as ImpactStory and Altmetric.com to get a broader picture of the attention that your (digital) research outputs receive  Data citation counts WHAT ARE THE ALTERNATIVES? Four reasons to stop caring about the h- index by ImpactStory
