Talk:Church of Christ in China

Question on sources
The sources for this article include archival documents (footnote 2) and interviews (footnote 6). My understanding is this diverges from Wikipedia policy. Are these sources from a published book or article? If that is so, then the book or article needs to be cited. In any case, the references aren't clear; for example, what is "UCA" in footnote 2? What is Boynton and Boynton? Can someone help clarify this? --Greentina (talk) 02:21, 15 March 2012 (UTC)
