Summary of responses to query about research impact factor tools and tips
Treat with caution – different institutions and subject areas recognise different metrics differently and some don’t recognise them as reliable measure of impact. Advise them about the tools but advise them about possible limitations too. The Sciences and Health Sciences seem to have more reliable data so tend to be able to rely on these more.
ISI suite of products is market leader. Thomson ISI is a key player and the most long-standing founded in 1960.
Web of Knowledge and SCOPUS seem to be the two main competitors for this market. Several institutions are looking at SCOPUS but it is expensive (no price given). SCOPUS enables you to see the number of citations for journal titles. SCOPUS has a better range of citations than ISI for some subjects.
Web of Knowledge is the source of all ISI citations used in other product lines. It allows you to do a citation search or to find an author’s h-index rather than just looking at the impact of a journal. The h-index is an index to quantify an individual’s scientific research output put forward in 2005 by the American physicist, Jorge Hirsch. Use the Author Finder tool in Web of Knowledge for this. The Journal Citation Reports product in Web of Knowledge includes a number of indicators including the Journal Impact Factor. You pay extra on top of your WOK sub to access JCR. JCR is published annually and comes out 6-7 months after the end of the year. In-cites can be used for looking at an institution. http://isiwebofknowledge.com/incites/.
Other tools people mentioned were:
http://www.scimagojr.com/ - developed from rankings in Scopus
Sci-Bytes http://sciencewatch.com/dr/sci/ - gives small snapshots of the statistics from Journal Citation Reports, e.g. the "Top 10 journals in education", in the latest issue.

SciImago - a free website based on the Scopus dataset.
Google scholar plus Publish or Perish software which you can download offers better range of citations for SOME disciplines
Eigenfactor.org – free website
The Washington and Lee University School of Law http://lawlib.wlu.edu/LJ/index.aspx - a useful tool for law researchers.
Some very kind people sent lists of useful reading and further information, including introductions to the topic:

Citation Analysis - how to ...
All researchers will be familiar with calls to measure or prove your impact through citation analyses. Whether you agree or disagree with such measures of quality, these Step-by-step guides to citation analysis for UL researchers using Web of Science (ISI) and Publish or Perish (Google Scholar) will be useful.
Guide to using Web of Science
Guide to using Publish or Perish
Journals
If the Web of Science does not cover the journals or books in which you publish (check the Master List here), you can apply to have a journal included. Click here for selection criteria and an application form.
Conference Proceedings
For those disciplines where Conference Proceedings are primary publications, the recent inclusion of Conference Proceedings in Web of Science should improve citations.
Books
Books are not covered by Web of Science, nor are there plans to begin coverage of books. Those researchers who publish mainly in books may be interested in this post suggesting alternative measures for assessing impact in the AHSS.
Publish or Perish , a Google Scholar citation analysis tool from Anne-Wil Harzing, can be useful where Web of Science results do not appear to give a fair reflection of your research output.
For more information on Citation Analysis, the h-index and Journal Impact Factors see the library webpage (www.ul.ie/library) at Supporting Research -> Research Publication & Dissemination here, or go directly to the site here.
