Again, as I've already pointed out, doing a theme summary of 'Hamlet' is really no different from doing a character list.  The themes of 'Hamlet' are in 'Hamlet,' the same as the characters of 'Hamlet' are in 'Hamlet.'  It isn't complicated, the way some people try to make it.  And there is no "original research" in simply doing a theme summary, any more than there is "original research" in doing a character list.  Are you going to look at some book by Harold Bloom to find out whether Polonius is in the play, because otherwise you can't tell?  That would be nonsense, of course.  The same is true of the themes of the play.  The "source" for all the themes of 'Hamlet' is "Hamlet."  That is a fact.  And I have no idea where people are getting their strange and eccentric ideas of what a "theme" is.  Some people who have posted here need to go to Merriam-Webster online, and look up the word "theme."  A theme is a motif, a recurring idea.  That is factually what a "theme" is - look it up.  A final point, is it too much to ask that words should be spelled correctly in the article?  Look at what's there now  "soliloquy" is misspelled; "cemetery" is misspelled.  It looks terrible, and it's embarrassing.  Please, before you post something, just copy the text over to a text editor, and run a spelling check on it, since there doesn't seem to be a spell checker here.  It's great that people want to contribute, but passers-by who see the article with all those misspelled words are going to sneer and say that Wikipedia is crap.  Nobody wants that.  

Why was the original theme summary deleted? I suppose that section could be thought of as a starter to the more broader literary critisism section, but please explain why.
