Most college and university online databases are not free to the public, students must use a username and password to access them.
However, as you search the web, you may find online scholarly journals; these are "open access" articles that are free to the public.
Scholarly research has been changing as many journals are beginning to only be published online. These are called open access journals. An open access journal is defined as "a scholarly periodical that makes the full text of the articles it publishes universally and freely available via the Internet in easily read format..."
This means that you do not need to subscribe to any databases, or enter your RU ID number to access any of these free, scholarly journals.
