Thank you for post this information. There is a lot that can be done once the Free-Space page has been created. I see that you have already added Tags and a Category. I also added it here: Sources-Family_Genealogies
You can also add a "What Links Here" link to your source page. Here is the link if you want to try it: http://www.wikitree.com/Wiki/Special:Whatlinkshere/Space:William_Standley_%281720%29_Genealogy_Publication
It shows what profiles are using the source.
You could also add the information that Ellen posted above.
