Reformat references and citations (manually done) in Word into EndNote

Hi all,

My collaborators added citations and references by manually typing them in a Word document. Now I need to reorganize them into the format for the journal PLoS. Besides creating a blank library and manually adding/editing each reference in EndNote, is there a quick way to automatically import those into EndNote, set the right format, and then display them with the desired format of citation and reference in Word again? Thanks a lot! 

hi, there are about 70 references, none of them is previously added in any EndNote library. They were cited as (Author et al year), and the references were typed in a way different from PLoS. I use EndNote X2 under Windows Vista.
