AUTHORITIES.--(1) _Principal Sources_: The history of Anjou may be told partly with the aid of the chroniclers of the neighbouring provinces, especially those of Normandy (William of Poitiers, William of Jumièges, Ordericus Vitalis) and of Maine (especially _Actus pontificum Cenomannis in urbe degentium_). For the 10th, 11th and 12th centuries especially, there are some important texts dealing entirely with Anjou. The most important is the chronicle called _Gesta consulum Andegavorum_, of which only a poor edition exists (_Chroniques des comtes d'Anjou_, published by Marchegay and Salmon, with an introduction by E. Mabille, Paris, 1856-1871, collection of the _Société de l'histoire de France_). See also with reference to this text Louis Halphen, _Êtude sur les chroniques des comtes d'Anjou et des seigneurs d'Amboise_ (Paris, 1906). The above may be supplemented by some valuable annals published by Louis Halphen, _Recueil d'annales angevines et vendómoises_ (Paris, 1903), (in the series _Collection de textes pour servir à l'étude et à l'enseignement de l'histoire_). For further details see Auguste Molinier, _Les Sources de l'histoire de France_ (Paris, 1902), ii. 1276-1310, and the book of Louis Halphen mentioned below.
(2) _Works_: The _Art de vérifier les dates_ contains a history of Anjou which is very much out of date, but has not been treated elsewhere as a whole. The 11th century only has been treated in detail by Louis Halphen, in _Le Comté d'Anjou au XI^e siècle_ (Paris, 1906), which has a preface with bibliography and an introduction dealing with the history of Anjou in the 10th century. For the 10th, 11th and 12th centuries, a good summary will be found in Kate Norgate, _England under the Angevin Kings_ (2 vols., London, 1887). On René of Anjou, there is a book by A. Lecoy de la Marche, _Le Roi René_ (2 vols., Paris, 1875). Lastly, the work of Célestin Port, _Dictionnaire historique, géographique et biographique de Maine-et-Loire_ (3 vols., Paris and Angers, 1874-1878), and its small volume of _Préliminaires_ (including a summary of the history of Anjou), contain, in addition to the biographies of the chief counts of Anjou, a mass of information concerning everything connected with Angevin history.
