BIBLIOGRAPHY.--The Convention published a _Proces-verbal_ of its
sessions, which, although lacking the value of those published by
assemblies to-day, is an official document of capital importance.
Copies of it are rare, however, and it has been too much neglected by
historians. See F. A. Aulard, _Recueil des actes du comite de Salut
Public avec la correspondance officielle des representants en mission,
et le registre du conseil executif provisoire_ (Paris, 1889 et seq.);
M. J. Guillaume, _Proces-verbaux du comite d'Instruction Publique de
la Convention Nationale_ (Paris, 1891-1904, 5 vols. 4to); F. A.
Aulard, _Histoire politique de la Revolution francaise_ (Paris, 1903);
Mortimer-Ternaux, _Histoire de la Terreur_ (1862-1881), a work based
on and comprising documents, but written with strong royalist bias;
Eugene Despois, _Le Vandalisme revolutionnaire_ (1868), for the
scientific work of the Convention. A detailed bibliography of the
documents relating to the Convention is given in the _Repertoire
general des sources manuscrites de l'histoire de Paris pendant la
Revolution francaise_, vol. viii. &c. (1908), edited by A. Tueley
under the auspices of the municipality of Paris. For a more summary
bibliography see M. Tourneux, _Bibliog. de l'histoire de Paris pendant
la Revolution francaise_, i. 89-95 (Paris, 1890). (R. A.*)

It has a fine southern Romanesque cathedral of the end of the 11th
century, with a modernized interior, and a castle which from 1456
belonged to the Acquaviva family, dukes of Atri and counts of
Conversano. The convent of S. Benedetto is one of the earliest offshoots
of Montecassino. (See S. Simone, _Il Duomo di Conversano_, Trani, 1896).
Here, or in the vicinity, is the site of the unimportant ancient town of
Norba.
