It's a lot shorter than my parser versions, but it doesn't handle
multiple page numbers correctly (the second Doggone Williams
citation). You could probably handle this by processing the list of
split references.

Why not use the grouped regex alone? If you use finditer() instead of
findall() you get a sequence of match objects so you can use the named
groups.
