2. What is a “secondary
It is a database used to “locate” other
resources where you can find required
Example: Medline is a database where you
can find lists of periodical articles on
topics related to healthcare.
REMEMBER: you can only “cite” the actual
article and the journal it appears in. You
can NOT cite the secondary database. It is
only a resource for locating the article.
6. Subject Searching – Why?
Many secondary databases have “subject
headings”. Why search by “subject
heading” rather than “text word”?
Subject headings are more effective
because they enable you to search a topic
without having to remember all possible
synonyms an author might have used for
Ultimately, one should master both “text
word” and “subject” searching.
8. Subject Searching - Examples
Subject searching - provide a structured language
for you to use when searching for specific
topics in the literature.
