title: Can I specify multiple bibliography (BibTeX) files in Pandoc Metadata?
body: <p>Often, scientific journal websites and other sources offer downloadable <code>*.bib</code> files for referring to individual articles. If I use these, I like to keep them as they are instead of merging them into a single file. On the command line, several files can be specified by passing the <code>--bibliography</code> option multiple times. Can I also list multiple files in the YAML metadata inside the <code>*.md</code> document itself?</p>
