The Web of Knowledge is a portal in which you can search multiple ISI databases including Medline, Web of Science, Current Content, Biological Abstract & others.

22 Scopus Positioning itself as an alternative to ISI More journals from smaller publishers and open access (+19,500 journals; conf proceedings) Source data back to Excellent for physical and biological sciences; poor for social sciences; does not cover humanities or arts. Better international coverage (60% of titles are non-us) Back to 1996! (e.g. citation data for the last decade only) Easy to use in searching for source publications; clumsy in searching cited publications. Citation tracker works up to 1000 records only.

23 Google Scholar Better coverage for all citations as it retrieve web! More coverage of references also gray literature! Coverage and scope? Inclusion criteria? Very limited search options No separate cited author search Back to 1990 NOT more! Free!

24 Web of Science (Now Thomson Reuter ISI) Covers around 11,000 journal titles and 110,000 conference proceedings & alos 200 book series divided between SCI, SSCI and A&HCI. Over 40 million records! Electronic back files available to 1900 for SCI and mid- 50s for SSCI and mid-70s for A&HCI. Very good coverage of sciences; patchy on softer sciences, social sciences and arts and humanities. Full coverage of citations.

26 Web of Science If a journal is in Web of Science, it means it should have Impact Factor & vice versa. Don t confuse Web of Sciences Journals with ISI Master list Journals! Web of Science indexed about 11,000 Journals while ISI Master List 15,000 Journals.

27 The Journal Impact Factor The Journal Impact Factor is calculated for those journals only which are indexed & included in Web of Sciences Databases, NOT more! The database which contain the Journal Impact Factors is Journal Citation Report abbreviated JCR.

28 What is Journal Impact Factor? The average citation frequency for articles published in a journal, or how many times, on average, during the study year the articles that appeared in the 2 preceding years of that journal received citations in other (ISI) indexed journals only.

29 Impact Factor Calculation Citations in the current JCR year to articles published in the previous two years divided by the number of articles published in the previous two years. IF= Citations in 2007 to articles published in Total Papers

30 Citation Immediacy Index Impact Factor Source paper published in 2007 Cited reference published in 2007 Cited reference published in 2006 or 2005 All Previous Years Cited ½ Life

37 H-index was born! We need an Index both to include quantity & also quality of an authors' paper Productivity Impact Not affected by big hits Not affected by noise

38 The H-index: a definition The H-index is the highest number of papers a scientist has that have at least that number of citations. Nature (2005)
