Information Sources: Choosing and Finding the Right Source
Your first option is to search individual databases. Databases may be multi-disciplinary, covering many topics, or they may be subject specific, covering only one topic.
When should I search a specific database?
As you move along in your academic career you will become familiar with various databases within your discipline. By the time you are a graduate student you should be familiar with these databases. For example, health professions such as Nursing should use CINAHL, MedLine (which is a subset of PubMed), and PsycInfo as well as others (depending on the research topic).
When you are looking for information within a specific discipline, it is often more effective to search a single database that covers that topic.
One of the advantages to searching a subject specific database is that there are more ways to refine and limit your search, producing more focused results.
Academic Search Complete is very large database and covers many topics. Consider searching this database as well as your subject specific database if you are not finding enough results.
