We have many different databases to use to locate journal articles. If you're just getting started researching, a great place to get started is Academic Search Complete. It’s a multidisciplinary database, which means it has articles from journals that span nearly every subject.
If you’ve already gotten started, and are not finding what you need, look in some of the more subject specific databases.
You may also have luck visiting your home college’s library. They may have different databases and resources available and can also use interlibrary loan to get you articles and books from colleges and universities throughout Colorado.
