There are six ways to build your database in RefWorks:
Converting from another bibliographic management program such as EndNote
To organize the data, create folders for specific topics, assign descriptors (keywords) to references as you add them to the database, or use some combination of both. If you use descriptors to organize the data, select By Descriptor from the Search menu option to search and locate your references.
If you use folders, note that the same reference can be in several folders depending on your need. You can create a folder for each assignment, research paper, article etc. This keeps your references well organized.
