Guy Harris (talk | contribs) Use the page= and pages= parameter in {{rp}}, rather than putting the p. and pp. in directly. Use {{hyp}} in a hyphenated page number. Split reference from a section heading, and get rid of a blank line in the middle. Fix a link. Fix a page number to be the page with the quote. Hyphenate archive-url and archive-date. |
