When comparing

• Thumbshots
• The new Thumbshots Ranking Tool allows you to
  perform your own comparisons, and displays the
  results visually, making it easy to see both the
  rankings and comparative positions of pages in
  search engine results. URLs are represented by
  small circles, and these circles are connected by
  a line if the page appears in both engines you're
  testing. Mouse over a circle and the full URL of
  the page is displayed. (Sherman, Searchengine
  watch, April 18, 2004)

When comparing

• While the comparative results are interesting,
  they aren't always exactly the same as you'll see
  when doing a search directly on a particular
  engine. According to Stephen Lim, Executive
  Director of Thumbshots.org (the folks who created
  the tool), results may vary due to your locality,
  or from the tool hitting different data centers.

Citation indexing

• Authoritative articleAuthoritative work.
• Cited references records and journal article
  records.
• Tracking back who cited who?
• Scholarly communication biggest network.
• Research and assessment of topics and
  disciplines.
• Why useful for your RLS?

Citation Indexing

• The power of citation searching lies in the
  capacity to take a seminal article and uncover
  who the author was influenced by (who was cited)
  and go forward in time to discover how that
  seminal research affected newer works (who is
  citing it). ISI (a Thomson business, formerly
  Institute for Scientific Information) has allowed
  such techniques to be used by serious searchers
  for years by providing the means of searching for
  known articles or authors in the "cited
  reference" field of ISI's citation
  indexes.(Carol Tenopir)

Citation indexes

• Citation Analysis
• A. What are the most important journals?
• B. Is this researcher important?
• C. Are we connecting to others?
• D. How good is this collection?

On Dialog

• The Social SciSearch database is an
  international, multidisciplinary index to the
  literature of the social, behavioral, and related
  sciences, produced by Thomson Scientific. Social
  SciSearch contains all of the records published
  in the Social Sciences Citation Index.
• Social SciSearch offers some unique information
  retrieval techniques. In addition to the more
  conventional methods, Social SciSearch offers
  citation indexing, which permits searching by
  cited references. For records added since March
  1991, author keywords and KeyWords PlusTM can
  also be searched.

On Dialog 2

• SciSearch A Cited Reference Science Database is
  an international, multidisciplinary index to the
  literature of science, technology, biomedicine,
  and related disciplines produced by Thomson
  Scientific. SciSearch contains all of the records
  published in the Science Citation Index (SCI),
  plus additional records in engineering
  technology, physical sciences, agriculture,
  biology, environmental sciences, clinical
  medicine, and the life sciences.SciSearch indexes
  all significant items (articles, review papers,
  meeting abstracts, letters, editorials, book
  reviews, correction notices, etc.) from more than
  6,100 international scientific and technical
  journals.
• SciSearch is distinguished by many important and
  unique characteristics. Journal evaluation and
  selection is conducted on an ongoing basis. Many
  factors are considered when evaluating journals
  for coverage, ranging from the qualitative to the
  quantitative. The journal's basic publishing
  standards, its editorial content, the
  international diversity of its authorship, and
  the citation data associated with it, are all
  considered.
• Another important feature of SciSearch is
  citation indexing. Citation indexing allows for
  the searching of cited references. Since January,
  1991, author abstracts, author keywords, and
  KeyWords PlusTM were added as searchable fields
  on SciSearch.

Two powerful commands

• S CRcited reference
• S CAcited author
• S cabenoit g
• S crbenoit g, 2003
• S aurichards p
• Note The command Expand is useful here for
  names.
• SELECT CRJOHNSON WG, 1995?

11
Controversy?

• Is this researcher better than this one?
• Do you cite?
• Why do you cite?
• If scientific research is based on collaboration,
  that collaboration should be reflected on the
  citation network.

12
ISI

• In 1997 the reach of citation searching increased
  dramatically when ISI introduced ISI Web of
  Science, now part of ISI Web of Knowledge. It
  reflects the interrelated "web" of scholarship
  whereby a user-friendly web interface made
  citation searching accessible to end users. Web
  of Science is already popular in university
  libraries, and ISI is hoping the additional
  functionality offered under ISI Web of Knowledge
  will build on that popularity by providing
  additional content sources and databases, plus
  cross-file searching, beginning in December 2001
  (see www.isinet.com).(Tenopir, Carol)

Citation Searching considerations

• Inclusion of foreign research
• Second, Third, Fourth author
• Social Sciences
• Humanities
• Hard Sciences
• Citation Mining

Web of Knowledge

• Available at Simmons GSLIS
• One aspect of it is the Web of Science, an
  enhanced web version of the Institute for
  Scientific Information's citation indexes,
  including the Science Citation Index, the Social
  Sciences Citation Index, and the Arts and
  Humanities Citation Index. The Web of Science
  measures the impact of particular journals and is
  one of the sources used by the National Research
  Council to rank graduate programs. Our Web of
  Science subscription includes citations and
  references from articles in more than 8,000 high
  quality, peer-reviewed journals published from
  1994 to the present. In addition to articles,
  other document types indexed are letters,
  corrections, additions, editorials, and reviews.
  The Web of Science provides complete
  bibliographic data, searchable author abstracts,
  and cited references.

Journal Impact Factor

• What would you say if you discover that there is
  actually a way to measure the impact that a
  journal has on a certain field? What are the
  implications of this for collections and
  searching?

• Library Journal vs. Library Trends
