WWW vs. Periodical Databases
WWW Contains text,
images, sound, and video
Anyone can publish pages on the Web.
Numerous hits with many duplicates
Unregulated source of information
Periodical Databases Mainly text (HTML &
PDF formats) Access to specific
information High degree of
authority on the information found within
No duplicates

Searching Periodical Databases
Need to research articles, esp. scholarly
Greater concern for authoritative sources
More powerful “advanced” searching
Need newspaper archives/backfiles
![Page 5: Searching & Evaluating Resources](https://reader036.fdocuments.us/reader036/viewer/2022070408/568143f3550346895db07c42/html5/thumbnails/5.jpg)
Popular Vs. Scholarly Intended for a
general audience. Articles written by
journalists who may or may not have special training
Articles do not have footnotes
Magazines have advertising, photographs, and glossy pages
For Profit Not Peer-reviewed
Intended for an audience knowledgeable in the field
Articles are written by scholars, whose names are listed along with credentials
Articles are footnoted and list sources used
No advertising, few photographs, and usually printed on plain paper
Usually not for profit Peer-reviewed

Choose Your Sources Wisely
No matter how much time and effort that you put into your paper, it will be only as good as the sources that you use
Choose a variety of sources (reference materials, journals, essays, books, statistics, documented research, letters)
![Page 7: Searching & Evaluating Resources](https://reader036.fdocuments.us/reader036/viewer/2022070408/568143f3550346895db07c42/html5/thumbnails/7.jpg)
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
![Page 8: Searching & Evaluating Resources](https://reader036.fdocuments.us/reader036/viewer/2022070408/568143f3550346895db07c42/html5/thumbnails/8.jpg)
Selecting a Topic and Determining Keywords
After deciding on a topic, write down the topic in the form of a sentence or question.
Does ethnicity and class affect educational attainment in England?
Look at your question and pull out the most important words.
Ethnicity class education England
![Page 9: Searching & Evaluating Resources](https://reader036.fdocuments.us/reader036/viewer/2022070408/568143f3550346895db07c42/html5/thumbnails/9.jpg)
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.
ETHNICITY RACE RACISM MINORITY DEMOGRAPHY EDUCATION UNIVERSITIES COLLEGE ACADEMIA
STUDENT SCHOOL EDUCATIONAL ATTAINMENT BIAS PREJUDICE DISCRIMINATION ENGLISH BRITISH AFFIRMATIVE ACTION EQUALITY DIVERSITY
EQUAL OPPORTUNITY PROFILING
![Page 10: Searching & Evaluating Resources](https://reader036.fdocuments.us/reader036/viewer/2022070408/568143f3550346895db07c42/html5/thumbnails/10.jpg)
Group Concepts Group concepts together by
parentheses or quotation marks
“race prejudice” “higher educational attainment”
or
(race prejudice) (educational attainment)
![Page 11: Searching & Evaluating Resources](https://reader036.fdocuments.us/reader036/viewer/2022070408/568143f3550346895db07c42/html5/thumbnails/11.jpg)
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
![Page 12: Searching & Evaluating Resources](https://reader036.fdocuments.us/reader036/viewer/2022070408/568143f3550346895db07c42/html5/thumbnails/12.jpg)
Examples
higher w education bias n3 racial “racial profiling” which is the same
as racial w profiling
![Page 13: Searching & Evaluating Resources](https://reader036.fdocuments.us/reader036/viewer/2022070408/568143f3550346895db07c42/html5/thumbnails/13.jpg)
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 (use NOT carefully – it may omit results that you had not intended)
![Page 14: Searching & Evaluating Resources](https://reader036.fdocuments.us/reader036/viewer/2022070408/568143f3550346895db07c42/html5/thumbnails/14.jpg)
Examples
“racial bias” AND “higher education”
“higher education” OR “university”
(“higher education” OR “university”) AND “racial bias”
![Page 15: Searching & Evaluating Resources](https://reader036.fdocuments.us/reader036/viewer/2022070408/568143f3550346895db07c42/html5/thumbnails/15.jpg)
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” or root onward) found.
Wildcard key – Replaces a single character and makes it a “wildcard” for any letter in the alphabet.

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?
