download files into endnote X9

Hi, 

I am new to endnote (installed last year but used it on and off) and wondering whether there is an easy way to clean up my reference list. Specifically, I want to first download all files (approx. 40 items, one by one as they are from different sources) to my MAC and then importing everything at once into endnote. However, I have not figured out a way to do so and instead, I download and import items individually. It is very laborious…

Hope to get some help from the community,

Thanks, Cheng
