A Reader's Companion to A Civil Campaign by Lois McMaster Bujold, Compiled and Presented to Her by Members of the Official LMB Mailing-List to Celebrate the Silver Anniversary of Shards of Honor 1986–2011

Obviously the publisher and place of publication are part of the fun for the fans who created this. It is, however, scholarly in nature and discusses romance: Georgette Heyer's A Civil Contract is cited as "a major intertext" and there is an "Afterword: LMB’s continuing romance with romance." Here's a quote from the beginning:

Alone among LMB’s work, A Civil Campaign is dedicated not to a personal acquaintance but to four late queens of romance—Jane Austen (1775–1817), Charlotte Brontë (1816–55), Georgette Heyer (1902–74), and Dorothy L. Sayers (1893–1957). As LMB explains matters in the ‘Afterword’ to Miles in Love:

I’d been itching to write a Barrayaran Regency romance ever since I’d realised I’d given Barrayar a regency period. I dedicated it to four inspiring female writers. I’d read Charlotte Bronte’s Jane Eyre fairly early on, but I only came to Georgette Heyer and Dorothy L. Sayers in my twenties, when my reading branched out, and I’ve only picked up Jane Austen fairly recently. Heyer remains my favorite comfort reading—A Civil Campaign is very much a tribute to her—though there was a period when her inherent class-ism got up my nose.
