    ********  ENTRIES  ********
    
    Entries form the basis of a bibTeX database and are categorized by their type, such as a book, journal article, conference proceedings, etc.  Each entry type has a specific set of fields that are required in bibTeX; as a first pass, these fields will also be required in the OWL ontology.
    Note: all rdfs:comment values for the entries come from http://newton.ex.ac.uk/tex/pack/bibtex/btxdoc/node6.html.
