With the many sources of information we have available to us, we often find ourselves with too much information! We need some way to sort through it all. We need to know what sort of questions to ask to determine whether the information available will adequately answer our questions. At each stage of your research, different questions need to be asked. Some guidelines are given here.
Before you start searching, it is best if you can define your information need. If you know what you're looking for, you'll be better able to recognize it when you've found your answer. Also, defining your information need helps you know where to start looking.
Some questions can be answered while you are looking at your search results in a database or search engines. Know the content of the databases, read abstracts (if available), do author searches, look at subject headings, and notice publication information (for dates, places, and publishers). Other questions will be answered when you are looking at the publication itself or at the full-text in a database.
Finally, after you have read through a book, an article, or other publication, you should be able to answer questions about the type and quality of information that it gives.
It is important to remember that anyone can put up a web page, and there is no 'quality control' or editor for what you find on the Internet. Therefore, you must be ready to make your own evaluation of web sites, especially if you are going to be using them for research purposes. You will want to find out as much as you can about the authority, currency, relevance, and accuracy of the web sites you use. These checklists and other resources will help you ask the right questions.
