Webpages, blogs, online videos, and other resources you can find on the web can be great starting points for your research. Like books, web sources can help you grasp an understanding of the concepts, and give you ideas for search terms (keywords, key phrases) to use in a database search.
Depending on the assignment, you can cite some web resources as long as they are authoritative and credible. If that is the case, use the CRAAP Test or another tool to help you evaluate the resource. But be careful! Check your assignment guidelines. Some assignments do not allow web resources.
Although there are many search engines available, Google is the best known and one of the most accurate.

Librarians in the US and from around the world recommend the CRAAP Test as it's applicable to all source types, and it's easy to remember!
