Les Châteaux Royaux de Saint-Germain-en-Laye 1124-1789 : étude historique d'après des documents inédits, recueillis aux Archives Nationales et à la Bibliothèque Nationale
A 1909 historical study of the royal château at Saint-Germain-en-Laye, written by Georges Louis Houdard and published in Saint-Germain-en-Laye by Mirvault, for readers of French architectural and local history. Its pictures are engraved and drawn plans of the château, its courts and surrounding town, and gardens, many with dense lettered keys and hatched ground that a designer could use as reference for layered site diagrams and map-like graphics.
