Sir Tim Berners-Lee proposes “5 Stars of Linked Open Data“, the last of which is “link your data to other data to provide context”. Accordingly, I’d suggest you add a line (or lines) to your “Works” table, with the URIs of, say, the equivalent English Wikipedia articles, and/or, their DBPedia (data) equivalents.

Wikipedia has a Shakespeare bibliography whose list of links you may find useful. Lists of links for Male Shakespearean characters and female Shakespearean characters are also listed.
