New & updated resources – Essential Science Indicators & Journal Citation Reports

trlogo2SGUL have access to a new resource from Thomson Reuters –  Essential Science Indicators (ESI) which provides information on highly cited research. Further, Thomson Reuters have also released an update to Journal Citation Reports (JCR). More detail for each resource is given below. Please note that at present, both these resources are only available whilst onsite.  The previous version of Journal Citation Reports will be available until 2016 and can be accessed both on and offsite.

Essential Science Indicators (ESI)
ESI is a management reporting tool to view citation metrics for individuals, institutions, papers, publications, and countries in a field of study—as well as emerging research areas. For example, it can provide information for the following:

  • What are the most cited papers in immunology?
  • Who are the most highly cited authors in the field of molecular biology?

More information:

Journal Citation Reports (JCR)
JCR tool summarizes citations from science and social science journals and proceedings in the Web of Science database to provide various citation reports and metrics by journal title or category (ie subject) including:

  • Total Cites
  • Impact Factor – 2 & 5 year

Please note that Thomson Reuters advise to use Journal Citations Reports wisely, and that you should not depend solely on citation data for journal evaluation.

All of these resources can be accessed via the Library website > Resources > Databases > A-Z list

2013 edition of Journal Citation Reports® is now available.

The  2013 edition of Journal Citation Reports®  (JCR) is now available via Web of Knowledge.

JCR measures the impact factor of journals, the 2013 edition contains the data for 2012. The impact factor is a measure of the frequency with which the average article in a journal has been cited in a particular year. The JCR also lists journals and their impact factors and ranking in the context of their specific field(s).

Nature reports on Citation tools from Google Scholar and Microsoft

Last week, Nature News published an article “Computing giants launch free science metrics” which discusses free tools from Google Scholar and Microsoft Academic Search (MAS)  to calculate citation metrics, including the h-index and in the light of Scopus and Web of Science (both paid-for tools).

Google had previously announced the release of Google Scholar Citations (GSC).  Details of an author’s papers are kept in their profile which can be updated. Profiles can also be made public, allowing others to view it.  Example public profiles provided by Google Scholar can be viewed here Albert Einstein, Margaret Mead, Alonzo Church). Currently this feature is only available to limited users whilst in the development / beta phase.

Microsoft have provided a 3 minute tutorial to explain some of the features of MAS. Like GS, MAS also allows author’s papers to be kept in their profile and updated. Originally it focussed on Computing Science but now covers a much broader range of disciplines including Clinical Medicine. Citation data can be viewed by author, organisation, year and within discipline or across all disciplines.

Allyson Lister, PhD student at Newcastle University, has written a useful first impressions comparison of GSC and MAS, including a round-up of other articles which discuss these tools.

For more background on citation metrics and the different sources (eg Google Scholar, Scopus, Web of Science) used to calculate them see papers by Professor Peter Jasco and Professor Anne-Wil Harzing.

These type of  tools have to deal with incomplete, ambiguous or incorrect data and therefore any results need to be treated with some caution. However, they can still be useful, especially the free tools if that is the only option available.

Web of Knowledge – new interface

On 17th July Web of Knowledge will be upgrading to version 5.

Web of Knowledge is the platform used to search the Web of Science Citation Indexes, which can be used to find citing articles, as well as view links between articles using citation mapping and citation reports.

The interface layout is the same.  Changes focus on numerous functional enhancements to search, display, citation metrics, results management and analysis.

Database Discovery: Citation Indexes (Web of Science)

What is it and how can it help me?

Produced by Thomson Reuters, Web of Science is made up of four citation indexes covering Science, Social Sciences, Arts & Humanities and Conference proceedings.  As well as being able to search for articles using a range of criteria, eg author, article title, topic, Citation Indexes are also able to create Citation Reports for authors, providing data such as the h-index, citations per year and publications per year.  Citation Maps provide a visual representation of connections between articles, and the Analyze Results tools is an easy way of looking for trends and patterns in your results.

Further, the Cited Reference Search allows you to find articles that cite a particular article or author.  You can set up emails alerts to inform you when a paper or author is cited.

What is the coverage?

There are four Citation Databases:

–         Science Citation Index Expanded (1970-present) – around 8,200 journal titles

–         Social Sciences Citation Index (1970-present) – around 2,800 titles

–         Arts & Humanities Citation Index (1975-present) – around 1,500 titles

–         Conference Proceedings Citation Index- Science (1990-present)

How do I access it?

There are various possible routes to access…

– For on-site access click here.

– Login to MyAthens; from the Resources tab, select Web of Knowledge, and then click on the “Web of Science” tab.

– From the A-Z list of databases on the Library website, click on C for Citation.

NHS staff can only access this service on-site, on a Library PC.

How can I get more help?

The Library website provides a number of guides and helpsheets including “Cited Reference Searching using Citation Indexes”, which covers the basics of looking up an article to find citing sources.

To learn more about the full functionally of the citation indexes, take a look at the training section of the Thomson Reuters website to view a tutorial on Web of Science.

Database Discovery: Journal Citation Reports (Web of Knowledge)

What is it and how can it help me?

Produced by Thomson Reuters and part of Web of Knowledge, Journal Citation Reports (JCR) provides citation data and metrics (including Impact Factors) in order to evaluate and compare journals.

You can choose to view data on a specific journal, all journals, or a group of journals by Subject Category (e.g. Medicine, General & Internal), Publisher (e.g. Nature Publishing Group) or Country (e.g. England).  A summary table includes key factors such as Total Cites, Impact Factor, Immediacy Index, Cited Half-life.  The full report can be viewed by clicking on the journal title, showing detailed breakdown of the metrics and trend data for the journal.

What is the coverage?

There are two editions of JCR.  The Science Edition covers over 5,900 scientific, technical and medical journals from 1998.  The Social Science Edition covers over 1,700 social science journals from 1998.  As the information provided is based on the number of citations in a given year, the most recent year currently available is 2008 (known as a JCR year).  JCR year 2009 will be available in summer 2010.

How do I access it?

Research shows that more researchers cite fewer, newer papers

New research published in Science, July 18, shows that as more scholarly and research journals are available online, researchers cite fewer, newer papers. Reported here on the National Science Foundation website:
http://www.nsf.gov/news/news_summ.jsp?cntn_id=111928&org=NSF&from=news

Two related phenomena, known as FUTON bias (FUll Text On the NET) and NAA (No abstract available) are discussed here:
http://ndt.oxfordjournals.org/cgi/content/full/18/9/1943
http://www.mayoclinicproceedings.com/inside.asp?AID=611&UID=
The findings suggest that articles which are more easily available online are favoured and therefore introduce a bias. The authors propose that this in turn could affect the course of medical education.
