Many, if not all, of the library databases allow you to create accounts within the database to store your articles and searches for future reference.
When completing a search, you will often see options such as "Mark" or "Add to Folder" . If you decide to use this feature you will need to create an account in the database. The good news is that once you create an account in an EBSCO database such as PsycInfo, you can add items from any of their databases using the same username and password. The same holds true for the ProQuest databases.
Saving your citations/articles within the database also allows you to export them into RefWorks all at the same time.
