When using images, you need to pay attention to copyright. The creators or the images you find on the internet may or may not allow you to reproduce them.
If you use Google Images, you can limit your results by using the Usage Rights button, which you will find at the top of your search results, then selecting the categories that allow reuse.
Connectors (or Boolean Operators) can help you get better search results in a database.
Not everything is available on the internet for free. Find out what information is buried beneath the surface, and how to access it for free.
A library database is a special collection of information sources. They may or may not be available individually on the internet. What is nice about using a database is that it brings quality information from both free and "not free" resources and makes them available to you in one place. Database access from the Michigan Electronic Library (MeL) is free to you because you are a resident of the state of Michigan.
You need to use keywords and connectors (boolean operators) to search a database. Searches will not work very well if you type in sentences or questions.
You can use the databases to look for articles about how others have addressed the problem you have identified, or to find some general statistics or information about your problem.
