How to import listed references in to EndNote X7 from a manuscript ?

I am a beginner for Endnote. I had been written some manuscripts with references without using Endnote. I want to continue to writing manuscript on Pages with Macbook. At this time, I have to transport Word document references to Endnote for continueing. Please give me an idea!

Do you have access to a database with your citations.  There are numerous discussions which all conclude that it is far more trouble than it is worth to try to “import” a text based document of references into endnote.  What is your field of study?
