Hello Tammy, Great Question. Any way other than what everyone has been doing would be fine. ;-)
Nothing worse than looking at a source that everyone can not see with out paying for only to find out the link is no longer valid.
Best to make sure the data is worth dealing with first. If someone says something without sources, I would not use it.
Try to copy, type or capture a picture of the data. Post it any way you like no format restrictions.
Watch for copy right infringement. If you copy or type historical facts only, its ok.
Use a standard citation format, original source information. And then perhaps a link to persons site that assisted you. (If he used sources, only fair to source him for his work. )
Will add a link to citations to assist.
