Wa alaykum assalam,
I doubt you would need to quote the reference for every line of information within the article itself.
Placing an index-type page at the end would be a good idea with all of the references corresponding to the page number there. For example, if you make a particular statement, you could just write in small script (1) at the end of that statement, and then at the end of the entire article write (1) there and reference the page you got it from. I have seen articles set out like that many times. If that makes sense?
