Yes you do need to give full references of the site in the appendices at the end of the document, nut not the detail - but in the document itself, you can partially reference.
If you say on one ref "Fame website, pp 29-30, para ii, XYZ company California, 1922"
(it's rubbish reference but you get the structure)
then for future references where there is no other document referenced in between, you can say
"ibid, page 6" (or whatever)
However if you refer to Fame on ref, 1,2,3, someone else on 4, then come back to Fame for 5,6 for next refs (for example) you will have to redo the full reference for ref No 5 and start again with the ibid list.
I know what I mean, does this make sense to you?
