New Chemistry Citation Index on
CD-ROM Comes with Abstracts,
Related Records, and Key Words Plus
Number 3
Two weeks ago, I introduced you to the
new Biotechnology and Neuroscience Citation Indexes on CD-ROM.’ These are
two of the fastest growing fields of research
worldwide. However, we also launched recently the Chemistry Citation Jrra’exm
(CCIm). The CCI complements the work
that ISI@has been doing for more than 30
years in producing Index Chemicus@2and
Current Chemical Reactions@. 3
The rationafe for producing the Chemistry Citation Index on compact disk is
similiar to that explained earlier for the
Biotechnology Citation Indexm (BClm )
and the Neuroscience Citation Indexm.
(NC~m ). While most universities receive
the Science Citation {ndex@ (SCl@), it is
generally not available in chemistry departments in academic, government, and industrial institutions.
January 20, 1992
The CC1 also contains selective coverage in the area of biochemistry. For example, articles from biochemistry journals
covering structure identification and analysis, physical properties and their measurement, chemical reactivity, reaction rate and
mechanism, synthesis, and stereochemistry are included.
Also included are articles in biochemistry journals that describe the use of analytical tools-such as calorimetry, spectroscopy, gas and liquid chromatography, and
nuclear magnetic resonance—all of which
measure chemical properties. The only area
really not covered is chemical engineering, or the large-scale manufacturing of
chemical substances. Microbiology, cell
processes, and genetic engineering are covered in the Biotechnology Citation Index,
which is totally compatible with the CCI.
Citation Indexing in Chemistry
Chemistry
Citation Index’s Scope
The CCI coverage is extensive and includes more than 330 core chemistry journals that are completely covered. In addition, thousands of r@icles are selectively
culled from the 4,000 plus other journals in
our database. All areas of chemistry, including organic, inorganic, analytical, and
physical chemistry are included. In addition, polymer, computational, orgartometallic and materials chemistry, and electrochemistry are covered.
In the early days of the SCI, I often described the advantages of citation indexing
in chemistry.4-6 Many of my f~st search
examples were based on my experience as
a chemist. But there have been others who
have demonstrated the unique powers of
citation retrieval in chemistry.7,8
Recently, W. Todd Wipke of the University of Crdifomia, Santa Cruz, extolled
the advantages of citation indexing for information retrieval in chemistry, particularly in connection with searching chemi-

One of the main advantages of the CCI
is the access it gives the user to the most
recent information available. Updated every other month with a yeti-to-date cum,
this service provides data three months
sooner than any other source available. Each
annual cumulation supersedes the interim
indexes.
Ofcourse,ourregular
features-searchable abstracts, Key Worak PlusN, and Reincluded. The exclulated Records-are
chemical reaction or, at the least, would
involve searching through many unrelated
papers.
Searching on the basis of chemical nomenclature has always had inherent problems, but you will be surprised how these
difficultiesare overcomein RelatedRecordsm
searching,
We would expect that most chemistry
departments would continue to use either

the topic, each could be used to augment

sive 1S1Key Words Plus feature, in addition
to title and author-supplied words, identi-
fies recting words or phrases in a paper’s
list of cited referenms. I have described
this feature in detail in past essays. 11,12Related Records is a navigational tool that
displays articles sharing one or more references in common (see Figure 1). Using
these tools, the researcher, for example,
can determine how a recent discovery was
confirrmxi, applied, improved on, extended,
or corrected.
The CC1, presently only available for
IBM compatible PCs and NECS, sells for
$1,950 a year. A free trial is available. Write
