When you evaluate information sources you could use particular criteria known as the CRAAP test. If your sources pass the test then you can use them for your papers.
Determine whether there is a particular time range within you have to locate information sources. For instance, if you want to find information to discuss a classic film you will not necessarily need recent information. However, if you want to discuss adoption from the perspective of gay and lesbian parents you may need to find recent information.
Determine how closely a piece of information aligns with your information needs. You will find many sources about your topic but you will need to specify which information is suitable for the type of paper you are writing or for the argument that you want to develop.
Determine whether the author, creator, or publisher of the information source is an expert on the topic or discipline.
Determine whether the information you located is correct and true.
Determine the reason the information exists.
