As I was checking the references for which I did include quote tags (ex. aconit, nappelle, spermatique, etc.), I found no quotation marks around the text. MH showed me how to fix this by surrounding the quote tags with cit tags. For example:

<p><cit><quote>s. m. Espece de plante veneneuse.</quote></cit></p>

This should now surround the text with the French guillemets.

MH also suggested that I use title tags to distinguish the title of the article and the title of the source. Ex.

<bibl><title level = "a">Aconit</title>, <title level="m">Dictionnaire de l'Académie française en ligne</title> (1694), The ARTFL Project, Department of Romance Languages and Literatures, University of Chicago, Internet, 24 août 2009.</bibl>

Title level = a should enclose the text in guillemets and title level = m should render the title of the source to italic font.
