Library Databases
and
Key Word Searches Why should I use
the Library Databases
when I can use ? When we search for Animal Rights in Google we get more than 66 million hits. Even when we narrow our search to include only scholarly articles.... Can you imagine how long it would take you to read 1 million scholarly articles? Library Databases Google VS. PWHS and other libraries around the world pay a lot of money to provide databases to their students and faculty. The articles on the databases are not available on the "free web." is on the "free web"--you do not have to pay to access its contents. Unfortunately "free" is not always better. Anyone with the right equipment can post whatever they want on . A website might look credible and contain completely false information. The materials found on the databases are peer-reviewed!! INFORMATION OVERLOAD!! It can be hard to find what you're looking for when there is information on EVERYTHING. Library databases are usually designed for a specific audience (high school students vs. college students) or are geared towards a specific subject (Opposing Viewpoints has information specifically on Social Issues). Key Word Searches When you enter words into a search box, the database scans every piece of material within the database.

Find phrases by using quotation marks: "Childhood Obesity". Ms. Mulroy's Guide to: The database searched through all of the articles for these words individually. There is not one article that contains each of these words. NO RESULTS!!! There are a few things to keep in mind! When you are using a search box, you should always use KEYWORDS.
The keywords are typically nouns. Ex. When searching for:
“The effects of fast food on Childhood Obesity”
EXCLUDE “the effects of” and "on" When two words go together, they are considered a phrase.
If you put quotation marks around the two words, the database will search for the word combination instead of each word separately. Nesting Ex. Fast + Food = “Fast Food”
