To ensure you have access to the large number of journals the library subscribes to, make sure you access all databases, even open access databases like PubMed, through the library's A-Z Database list or links on library guides like this one. These links will authenticate you as a Creighton user and provide you with full text when available.
If you are looking for a specific article, the easiest way to find the full text is to search for the article in JaySearch, available from the library homepage and further down this page.
If you want to know if the library subscribes to a particular journal, search for the journal in the JaySearch Journal Search.
