Generally, the answer is No. You would have to look at each profile to see the sources attached, then look for the source somewhere. If you are lucky, someone has attached a link to the source online. Many sources are not online, so you won't be able to look at them unless you can get to a library or archive that has the source. Also, if the profile is part of a One Name Study, the study page may have a link to the source.
I say "generally" because some sources are listed on FreeSpace pages, and you may find the actual source there.
