You can't do anything of that sort on site. You can however use the Way Back Machine website to retrieve old versions of webpages. Try plugging in your profile's URL. Then you can cross-reference with your current list.
I'm not sure if this would work. I believe it would only pull the code from the page, not necessarily the contents as it requires a database pull to find that.
Depending on how many years ago it was, I may have an old DB backup that could possibly have that information? Do you know when that was?
