I have nine books in this series, quite old, no ISBNs.  They are: La Personnalite, L.O.N.U., Contrebande et contrebandiers, Les Rhythmes biologiques, Les Grandes dates de l'antiquite, La Question scolaire, La Litterature latine du moyen age, Les Langues romanes, La Philosophie medievale.  If you are interested in any of these,  please PM me.  I'm open to a deal for some or all.  I haven't posted them because it's so tedious without ISBN's.
