It need :
  in thesaurus, a category named EDITORS

  isbn separator editor separator collection.
  for example :
  2204 -- Cerf -- Cogitatio fidei
  2204 -- Cerf -- Le Magistère de l'Eglise
  2204 -- Cerf -- Lectio divina
  2204 -- Cerf -- Lire la Bible
  2204 -- Cerf -- Pour lire
  2204 -- Cerf -- Sources chrétiennes

  when the user clic on ... on 225a line, the popup shows the list of collections from the selected editor
