Using Endnote for the first time

Hello,

I have a phd thesis which I have to organize according to author-date style. My references are improperly cited and are in different styles, so I just downloaded the Endnote trial version to help me organize references and bibliography. This is my first encounter with this program and I am having some difficulties.

So I have a cople of quesitons:

  1. I need to transfer each reference manually from my thesis in Word, into Endnote, is that right?

  2. My references are not properly written, so I thought that inserting them into Endnote and indicating the style I need, the program would automatically correct the references, or do I have to break down each reference myself and put each part of the reference in appropriate window? i.e. author in the author window, year in the year window,etc. This would require huge work ! I thought that Endnote did this, maybe I didn’t understand, could you please help me figure out how to do that? 

Thanks in advance
