LYX has support for BibTEX, which allows you to build databases of bibliographical references to be used in multiple documents. Select Insert Lists & TOC BibTEX Reference to include a bib file. Click on the resulting ``BibTEX Generated References'' button, and you will get a BibTEX dialog. In the Database field, type what you would type inside the braces of a \bibliography{} command5.2. Similarly, in the Style field, type what you would type inside the braces of a \bibliographystyle{} command.
After you've done this, you can use citations from any bibliographies you're including with Insert Citation Reference (see Section ). LYX will take care of running BibTEX. The box in the Citation dialog will show a list of all the references in your bib file.
