Note: This pub series was created in 1974, first to accomodate heretofore unpublished works of higher standard than the usual Anticipation series, but soon resorted to reprints of previously published titles from the "Anticipation" and "Angoisse" series.

• Can be split into two sub-series : "Les lendemains retrouvés" (SF; even numbers) and "Horizons de l'au-delà" (Horror, Fantasy; odd numbers).
• #23, theoretically part of the "Horizons de l'au-delà" sub-series, was never published.
