Before you begin Before you begin your search consider the following 1. What UNIQUE WORDS, DISTINCTIVE NAMES, ABBREVIATIONS, or ACRONYMS are associated with your topic? These may be the place to begin because their specificity will help zero in on relevant pages. 2. Can you think of societies, organizations, or groups that might have information on your subject via their pages? Search these as a “phrase in quotes”, looking for a home page that might contain links to other websites on your subject. 3. What other words are likely to be in any Web documents on your topic? 4. Do any of the words in 1, 2, or 3 belong in phrases or strings -- together in a certain order, like a cliché? Search these as a “phrase in quotes”. (E.g., “affirmative action” or “communicable diseases”) 5. For any of the terms in 4, can you think of synonyms, variant spellings, or equivalent terms you would also accept in relevant documents? 6. Can you think of any extraneous or irrelevant documents these words might pick up? You may want to exclude terms or phrases with -[no space] before each term, or AND NOT What BROADER terms could your topic be covered by? When browsing subject categories or searching databases on your topic, try broader categories.

Building your search Building a query requires the use of Boolean operators that allow you to refine and extend the terms of the search. The Boolean operators most often seen are:

• AND - All the terms joined by "AND" must appear in the pages or documents. “+" also used for AND. • OR - At least one of the terms joined by "OR" must appear in the pages or documents. • NOT - The term following "NOT" must not appear in the pages or documents. "-" also used for NOT. • FOLLOWED BY - One of the terms must be directly followed by the other. • NEAR - One of the terms must be within a specified number of words of the other.

Information quality It is necessary to carefully evaluate any information you find on the internet. The quality of information can vary a great deal. You must ask yourself the following questions: • Who is the author/publisher of the material? • Are they a reputable source? • What are their reasons for providing this website? • Are they impartial or biased towards a particular viewpoint? • How up-to-date is the website? • How recently were the web pages updated? • Do all the links work? • Has the information been well presented? • Is the site easy to read and to navigate? • Can the information be accessed all the time and at an acceptable speed?

Check out the help section on any of the search engines you use as they often have good hints and additional options for searching.

Referencing It is important to reference any material you use from the internet as you would with any textbook or journal article. The principles of referencing internet sources involve the same basic principles. Additional details you need to note include the complete url for the page you have referred to and the date on which you accessed it. A guide to referencing which includes examples is available in the Library.
