Note: The name of this publication series has been regularized as it's quite variable with time ("Science-Fiction", "Science-Fiction-Anthologie", "Triangle-Science-Fiction" or "Spécial Richard Bessière"). Bibliographically speaking, it's a mess with titles reprinted or simply re-issued or re-bound with a different cover and a different number (probably because of their distribution via the newsagents circuit, see the case of some Galaxie-Bis from OPTA or some Satellite titles), incoherent data (e.g. a 1976 DL with a 1977 copyright) or out of phase catalogue at the end of the books. Titles are dated from copyright. Note slight reduction in size from #21 (or #20) onwards.
