In a recent (January 25, 2013) post over on The French Genealogy Blog, blogger Anne Morddel writes about The Cabinet des Titres, the Cabinet of Titles, a part of the French manuscripts collection at the Bibliothèque nationale de France, the French National Library. Included in the Cabinet are such things as d'Hozier's Armorial général de France and such other manuscripts and books as the Armorial général des registres de la noblesse de France, and a whole bunch of other stuff of use both to genealogists and to heraldry enthusiasts. The post has several links to some parts of the collection, and other parts (the Armorial général de France, for example) can be found by doing a simple search on the website of the National Library.
It's a short but very informative article, giving some background that I hadn't seen before on the d'Hozier's and the Armorial général, as well as introducing me to some new-to-me volumes available at the National Library's website. If you have an interest in French heraldry, I suggest you go read the article and follow the links to see what's available. (And, of course, if you have an interest in French genealogy, the entire blog is a great resource.)
