Effective Information Searching
Learning Outcomes
Construct effective keyword searches
Choose appropriate databases according to needs
Navigate and search SciFinder Scholar and Web of
Science’s Science Citation Index to find chemical
information and literature
Access the fulltext of journal articles in three ways
Identify and describe Library services provided for
final-year students
SEARCHING SKILLS
•
Truncation
– Useful to find words in variant forms
– Search all words that start with the same characters
– Represent multiple characters
– Placement of truncation symbol is significant
network*
net*
•
Wildcard
– Useful to find words in different spelling, singular/plural form
– Represent zero or a single character
•
Phrase search
– To search multiple keywords as an exact phrase
• E.g. anionic analytes
VS
Behavio?r
Wom?n
(detect* OR sens???) AND
anion*
– With limitations
e.g. “anionic sensors” CANNOT find titles with “detection of anions”,
“signal the presence of anionic analytes”, etc.
•
Combining the use of AND, OR, AND NOT
– Useful to narrow down, expand your search
– To exclude unwanted concepts
– Use brackets to set search priority
((internet OR network)
AND securit*) AND NOT Asia*
The Steps
1.
Define your search topic
Be specific; try to write it in the form of a question.
Is pollution of groundwater a problem in Hong Kong?
2.
Identify the main concepts
Ignore “soft” words or connectors e.g. effect, improve, impact
pollution
groundwater
Hong Kong
3.
- variant endings
Create a list of possible search terms
pollution, pollutants, pollute, pollut*
groundwater, underground stream*
Hong Kong
4.
*
Combine your search terms appropriately
pollut*
AND – narrows search,
use between concepts
OR – broadens search,
use between synonyms
and
(groundwater or underground stream*)
and
Hong Kong
( ) – orders search,
use to keep your
synonyms together –
one concept
Recognize the Importance of
Using Journals in Research
• Why reading journal articles?
• Effective searching of CHEM.
and related journal articles in
Google? Google Scholar?
SciFinder Scholar?
• Try finding publication title =
“Analytica Chimica Acta” and
article title = anion sensor
ELECTRONIC DATABASES

Science Citation Index Expanded (Web of Science)
Indexes 5,900+ major journals across 150 scientific disciplines with cited references.
Cited references listed in each article
Check journal abbreviations and
full title
“Times cited”: provides with a list of articles that
cited the parent article
Follow-up studies, similar
studies, etc. Later articles which
build on this one to some extent.
Related records which provide a list of articles that
share at least one same cited works in the parent
article
Full-text linking in some records
Sometimes referred to as
“cousins” – other articles that
build on similar studies.
