Folks, I've found 2 references to the same primary source in 2 different sections of the same wp article. Those references were numbered automatically. How does one go about "merging" those 2, so that the reference only appears once? I don't know if I've made myself clear. The same primary source is listed as references 26 AND 47. How can the article be changed so that there is only 1 reference, say 26, while changing the superscripted 47 to 26 in the text? Thanks, DennisPietras (talk) 02:31, 8 January 2017 (UTC)
