When to use subject directories When you are just beginning your search and have only a general idea of a topic. When you are interested in a broad range of information rather than a specific piece of information. When you are looking for a list compiled by an expert. This helps eliminate irrelevant pages and ensures quality results.

General tips to help with your online search Did you check your spelling? One small spelling error can make a huge difference. Are you using the right kind of search? Author and title searches look for known items. A keyword search looks for your terms anywhere in the document. A subject search will look for terms in a predetermined set of subject headings. This works good if you choose the right subject term; if not, you may get zero results. It's a good idea to browse subject headings if possible.
Logical operators Using"and" will find all your words, but they may appear in different parts of the document and in any order (hytertension and therapy). This will narrow your search. Using"or" will find either term and maybe both (therapy or treatment). This will broaden your search. Using "not" will exclude a concept (AIDS not HIV), will exclude documents containing the word HIV" and make your search more focused.
Evaluating sources Authority (What are the author's references?) Accuracy (Is the information reliable?) Objectivity (Does the information show bias?) Currency (Is the information dated?) Coverage (How in-depth is the information?)
Authority Who is the author? Check a biographical source, if possible. What are the author's credentials? Does the source list the author's occupation, affiliation, position, education or years of experience? Can you find a critical review of the author's work?
Accuracy Can the information be compared with other sources? Is the information reliable? Is the source edited by a reputable organization?
Objectivity Who is the intended audience? What is the purpose of the information? Is it to sell a product or to promote a political opinion? Is there advertising accompanying the source? Does the source represent a balanced view, or can you detect bias? Can you find a critical review of the source?
Currency Includes the source a publication date or a "last updated date Is the date relevant to the type of information presented?
Coverage Does the source provide information relevant to the subject or to your needs? Is it written in language you can understand? Is this source too general or too specific for your needs?
