WWW vs. Periodical
Databases

WWW




Contains text,
graphics, sound, and
video
Anyone can publish
pages on the Web.
Numerous hits with
many duplicates
Unregulated source
of information

Periodical Databases



Access to very
specific information
Relatively high
degree of authority
on the information
found within
No duplicates
Searching the Web





Government information/Web sites
Associations & organizations
Commercial sites
Current news (limited)
“Specialty” sites
Searching Periodical
Databases




Greater concern for authoritative
sources
More powerful “advanced” searching
Need to research articles
Need newspaper archives/backfiles
Developing a Search Strategy





Select a topic
Identify keywords
Identify synonyms
Group concepts and add connectors
(Boolean)
Use truncation and/or wildcard keys if
available
Selecting a Topic and
Determining Keywords

After deciding on a topic, write down
the topic in the form of a sentence or
question.


What is the relationship between minorities and
the high incarceration rates in some states?
Look at your question and pull out the
most important words.

Minorities / incarceration rates / states
Identifying Synonyms

Take your keywords and find other
words that also describe your topic.
Also write down narrower and broader
terms to help refine your search.



Minorities – African Americans – Blacks – Hispanics –
Latin Americans
Incarceration rates – prison rates – crime rates – prison
counts
States – geographic areas – regions -- Texas
Group Concepts

Group concepts together by parentheses
or quotation marks
“incarceration rates” “state of Texas”
or
(incarceration rates) (state of Texas)
Proximity connectors



w or w5 (“with”) – searches for two
terms in the order typed
n or n5 (“near”) – searches for two
terms in any order
“ “ quotation marks – groups terms
together as a phrase
Examples



African w American
rate n3 crime
“state of Texas” which is the same as
state w of w Texas
Add connectors

Connectors (Boolean)
AND-both terms must appear together in
the record (narrows search)
 OR-either term appears in the record
(broadens search)
 NOT-placed before term omits all
records featuring this term in them

Examples
“African American” AND “crime rate”
“Hispanic” OR “Latin American”
(“crime rate” OR “incarceration rate”)
AND minorities
Use truncation and/or wildcard
keys if available



Both use a special key (*, ?, #, $) depending
on the source used
Truncation - When key placed at end of term,
all variations of word (from “trunk” onward)
found.
Wildcard key – Replaces a single character and
makes it a “wildcard” for any letter in the
alphabet.
Examples

minorit*



minority
minorities
Wom?n



women
woman
womyn
“incarceration rate*”
AND minorit*
OR
Crim* AND wom?n
Evaluating Sources (ABC’s)
Audience
 Authority
 Bias
 Currency
 Scope

Audience


What age group/education
level/political affiliation/etc. is the





Scope




What does/doesn’t the work cover?
Is it an in-depth study (many
pages) or superficial (one page)?
Are sources and statistics cited?
If a site, does it offer unique info
not found in any other source?
Selecting a Search Engine


Use Search Engine Watch or Search
Engine Showdown to find and compare.
Choose only 2 or 3 search engines and
learn them well.

yourself on advanced options.
Familiarize yourself with the advanced
search, if available.
