Indexing – Workshop for researchers

Produced by the Department of Learning and Information Services November 2014 Session coverage

• Overview of how Citation Counting & measuring impact can help

• • • • Research Development Wheel Citation Counting & Impact in Context Journal/Article Impact Factors

• Impact factors can show the effect/influence of a piece of research in a particular area by seeing how many times others have cited it

• Knowing the impact of a journal can help in decisions about where to submit an article. High impact journals are seen more

• Re articles-Warning – just because an article has been cited a lot does not prove high quality- could be controversial

Publishing in Scholarly journals

• “I need to publish in high impact journals” • The REF

• High Impact journals have a higher reputation

Tools

JCR for Journal Impact/ Web of Science for Citation Counts

• JCR – This tool helps you check impact at journal and discipline level. Available in Science and Social Sciences editions.

(Alternatives in Scopus- under Analyze Journals -SJR- SCImago Journal Rank- shows prestige of a journal- & SNIP-Source Normalized Impact per paper- weighs )

• WOS – database of articles. Authoritative, multidisciplinary content covers over 12,000 of the highest impact journals worldwide etc.

• -Citation Counts -can provide proof of being read, or at least noticed. ( You can also do this in Scopus, & Google Scholar)

Journal Citation Reports (JCR) (Journal Impact Factors)

• Applied to individual journals and represent the average citation counts of papers published in an individual journal during a specified time (2 years or 5 years)

• Where can I find Journal impact factors? • Journal Citation Reports (Web of Science), go through Databases A-Z (http://www.wlv.ac.uk/lib/resources.aspx) – Can search for an individual journal or view a group of journals by subject category (Education & Educational Research, Nursing, Psychology)

• Test your skills: Journal Citation Reports

• 1. Perform a subject category search in JCR on your specialist subject for 2013 • 2.Sort the results by • 3.Add them to your marked list • Test your skills: Web of Science

• Perform an author search for Jamal Khatib, University of Wolverhampton • How many documents has he published? • Which is his most cited article? • Test your skills: Scopus

• Perform an affiliation search for the University of Wolverhampton • Who is our top collaborator? • Which source published most of our articles? Research pages including guidance on- Impact

• http://www.wlv.ac.uk/lib/research.aspx e.g. Journal Impact Factors

-Journal impact factors are applied to journals and represent the average citation counts of papers published in that journal during a two year time frame.

Number of times articles published in Cell during 2007-2008 were cited in indexed journals during 2009 –––––––––-–––––––––––––––––––––––––––––––––––––– Number of “citable” articles published in Cell in 2008 and 2007

That is: Cites in 2009 to items published in 2008 + 2007 = 9533 + 12554 = 22087 Number of items published in Cell in 2008 + 2007 = 343 + 366 = 709

Impact = Cites to recent items …………………………….22087 = 31.152 Factor Number of recent items published……….. 709

Look within subjects/disciplines, or specific journals http://www.wlv.ac.uk/lib/resources.aspx

Journal Citation Reports

• You can go straight here from our Databases A-Z – choose the letter ‘J’ JCR Journal impact factors- showing which journals have the highest impact- those with highest impact likely to be most read, and cited, therefore spreading your research further

See the impact of a specific journal

JCR Impact factors of ‘Nature’

Look within subjects/disciplines

See the highest impacts in a subject discipline, e.g. ‘Nature’ is ‘Multidisciplinary Sciences

Think about which might be the highest impact factor journal in your own disciplines-

• Oncology?

• Engineering: Chemical?

• GeoSciences?

Impact of journals in Scopus

Web of Science • Select this from our Databases A-Z – choose the letter ‘W’

WOS Citation Reports- seeing the amount of times an author or their work have been cited- provides evidence that you are being read and cited.

Find info on an ‘author’ from the ‘University of Wolverhampton’

Create a Citation Report

Citation Report

Search for specific references

As with all useful things you find you can save/send to RefWorks etc.

H-Index & Citation Counts see Impact advice from Researchers pages

• The H-index is a calculation of how many times a researcher’s papers have been cited.

• E.g. an H-index of 27 means that the researcher has published 27 papers which have all been cited at least 27 times by other papers.

• The H-index can help to measure the impact of a researchers work and compare individuals within the same discipline, especially relevant to the sciences.

• A Citation Count is the number of times an article is cited by other articles.

Alternatives to Journal Citation Reports

• SJR - SCImago Journal • SNP - Source Rank - based on the belief Normalised Impact per that ‘not all citations are Paper - The SNP measures created equal’. by weighting • Takes into account the citations based on the total differences in citation behaviour number of citations in a subject between subject fields and is field. weighted by the prestige of the journal, meaning that a citation • Where do I find the SJR? from a journal with a high SJR is worth more than one with a Scopus or low SJR. http://www.scimagojr.com/

Summary

• JCR – long established

• SJR & SNP – can be used alongside the JCR or when a journal is not included in the JCR (British Journal of Midwifery)

• Helpful for – finding where to publish
