These fields provide the minimum information that you must have for a citation.
The required fields are marked with an asterisk (*). All the sources that you have cited, either in previous documents or in the current document, appear under Master list. If you open a document that includes citations, the sources for those citations appear under Current list. This is useful, for example, if you write research papers that use many of the same sources.
The Source Manager lists every source ever entered on your computer so that you can reuse them in any other document. To add a citation, a works cited list, or a bibliography to your document, you first add a list of the sources that you used.
