[How Library Stuff Works, McMaster Libraries]
Always remember to evaluate the quality of the site you are viewing. Don't believe everything you read unless the information comes from a reputable or reliable source.
Consider authority, accuracy, objectivity, currency, and completeness as you evaluate whether to utilize the information found on a particular Web page.
Whether you are searching for books in the Five College Library Catalog, or searching for scholarly articles in a library database, it pays to be organized as you start your search. Break down searching into a three step process.
Write down as much information about your topic as possible. (You can use encyclopedias and other reference books to help gather background information). Answer the following questions:
Then, try to summarize what you are looking for in one or two sentences.
EXAMPLE: I would like to learn about the lead in drinking water and its toxic effects including the Flint Michigan water crisis.
Using the information in Step 1, list the main concepts of your topic.
EXAMPLE: lead, drinking water, toxicity, Flint Michigan
Now create a list of synonyms of your key concepts. Think broadly, think narrowly! This step is helping you expand your search by expressing your query in a variety of ways. If you get too many results, then you can work on focussing your search.
You will use the word lists you developed in Step 3 to create search strategies. Use "OR" between synonyms and "AND" between concepts. For instance:
(lead) AND (water OR drinking water) AND (health) AND (Flint Michigan)
