Choral Public Domain Library

Help!! I need to find ANY choral music by the french composer Jean-François Le Sueur - born 1760 Abbeville northern France. It is his anniversary this year and the choir I conduct have been asked to mount a programme. Bibliotheque Nationale de Paris has only very badly photocopied scores. Any information welcomed!

The Italian on-line national library catalogue lists about 25 scores by Le Sueur (actually spelled "Lesueur"). Most of them are located at the conservatories of Milan and Naples, and they are old printed editions of the first half of 1800 or even manuscripts. There is nothing more recent.
