  1. Journal level impact assessment a diversity of new metrics Sarah Huggett Publishing Information Manager, Scientometrics& Market Analysis, Research & Academic Relations 25th September 2012

  2. A multi-faceted journal evaluation landscape

  3. Journal level metrics: why and how? Growth in output Appropriate use

  4. Results of a quick poll…

  5. Growth of scholarly communications ~3% per year

  6. Use of journal indicators “1) For journal editors and publishing houses the impact factors give market research information. Editors are able to approximate “their” journals’ standing in comparison to other thematically closely related periodicals.” “2) For libraries impact factors are useful for collection development, especially in combination with further indicators, primarily journal prices. Combined indicators, for example, Euros per unit of impact factor or a combination of this indicator with cost-per-use, may be effective for serial selection.” 3) Authors get hints on journals in which they can publish their research results (in case there are any authors in academia who do not know “their” appropriate periodicals).” “In no case is it possible to use a journal impact factor on the article level to evaluate the influence of an article, an author or an institution.”

  7. The skewness of citation distribution in journals Cumulative contribution of articles with different citation rates to total journal impact.

  8. Citations rates vary across fields

  9. Citations rates vary across article types Reviews Citations 20 18 16 14 12 10 8 6 4 2 0 Short communications Articles Years after publication

  10. Popularity metrics Impact Factor Source Normalized Impact per Paper

  11. Popularity metrics Journal Citation Reports

  12. Source Normalized Impact per Paper Available on Scopus Similar to Impact Factor, but considers 3 years Measures contextual citation impact Citations weighted by the likelihood of citation in the subject field of source Improvements in progress

  13. Prestige metrics EigenFactor Scimago Journal Rank

  14. Prestige metrics Journal Citation Reports

  15. SCImago Journal rank Freely available at scimagojr.com; on Scopus Similar to Impact Factor, but considers 3 years Self-citations limited Citations weighted by the SJR of the citing journal Improvements in progress

  17. Usage

  18. Citation Ethics Why do we cite? How should we cite?

  19. Citations: “a private process with a public face” “Reward or persuasion?
