Don't know where to start now that you've got your research topic?
After consulting the reference sources (dictionaries and encyclopedias) we've just described, you'll want to start looking for more depth on your topic.
Books, articles and DVDs can be found online through our research databases. Before we look at those, you need to further analyze your topic to identify the best terms to use in your search.

Identify Search Terms [Now we need to identify the key concepts and their related keywords.]
The best search terms will be the main concepts in your research topic. Take the time to choose them carefully, and your searches will be more successful.
Research question: How does globalization affect women in developing countries?
Search terms: globalization, women, developing countries (or specific countries (India) or continents (Africa))
Depending on which database you're using, you may find that the terms women and globalization are sufficient without the phrase developing countries. This is especially likely when searching for a book. There may be a book about women and globalization that has a chapter on developing countries, but the whole book is not on that particular aspect.
You should have at least two concepts for your research topic, only one will be too broad, making it difficult to research and to write about.
When searching in an article database, the more specific search terms are usually more successful, and you would probably use all three concepts.
Boolean Operator "AND"
Along with your subject search terms you'll want to use the boolean operator AND in combination with your search terms.
AND will make your search more focused, by combining two or more terms together.
AND requires that both (or all) terms be present in the results.
*Note that Google automatically assumes the word AND in between your search terms. Many library catalogs and articles databases do not.
Search question: How does Facebook use affect college students' academic achievement?
Search terms: facebook, grades, college
Search strategy: facebook and grades and college - requires all three main concepts be present in each item found in the results.
Boolean Operator "OR"
Along with your subject search terms and AND, you'll also want to use the "boolean operator" OR in combination with your search terms.
OR allows you to use alternate or similar terms to describe your topic.
OR will make your search more inclusive and less specific.
OR allows for either term to be present in the results, but doesn't require both.
Using AND with OR
Once you have your terms sorted out, you can then create your ideal search statement!
If you want to use a variety of terms to describe a particular concept (OR), then combine them with other terms using AND, look for the Advanced Search screen option that most databases have. They usually have several lines of search boxes making it easier to combine your terms in different ways. For example:
Keyword vs Subject Searching
Most searches can successfully start with keyword searching, but you might want to switch to subject searching if your results are off topic, too many, or too few. If you can find just one item in your results that looks good, take the time to look at the long record, and check out the subject headings assigned to that item.
