Sorry Mikey, I may have been the culprit. The practice on Wikitree, as I know it, is to make the citation as "reachable" as possible, so others can see the actual source, rather than trust that the person who did the citing got it right. I have found cases in which people have misinterpreted a source, or worse, "reinterpreted" a source to make it agree with their assumptions.
In adding my old genealogy work to Wikitree, whether a citation is to a book or an Ancestry citation, if I can find it for free online, it is easier for others to check. I have a lot of citations to books that I have looked at. No one can tell what the book really says unless they look at it. The easiest way for them to look at it is to go to an imaged copy online. If the publisher, publication date and place are the same, and the page number match, the citations are pointed to the same thing. (If the citation included a note that something was written in the margin, then obviously, they wouldn't be the same.)
For me, Wikitree is a collaborative site. Making a citation more accessible to others is a good thing, and I welcome anyone to add a link to an online source for one of my citations.
