In the post article form, it is "the name of the source." I took that to mean the original source (where it was first published). The Salt Lake City Tribune apparently reprinted the article from the Los Angeles Times. But if one provides a link to the LAT site version of the article, one gets a subscription password challenge, so I thought it best to provide a pointer to the Salt Lake City Tribune site version of the article instead. That also has a side effect (so I understand) of decreasing revenue to the Los Angeles Times, which apparently gets advertising money based on the number of hits to its website.
