Note: After the end for the series Bastei Lübbe Science Fiction Abenteuer (published approx. until 1995), Bastei Lübbe Science Fiction Action (published approx. until 1985), Bastei Lübbe Science Fiction Bestseller (published approx. until 1988) & Bastei Lübbe Science Fiction Special (published approx. until 1995), there was still another series: Bastei Lübbe Fantasy, published with 20XXX numbers. That difference became obsolete only around the year 2004-2007: the exact date still has to be determined.
