The Club del Misterio Series (early to mid-1980’s) predates the Etiqueta Negra Series (mid- 1980’s to mid-1990). Both Series are devoted to Crime Fiction. Both  have appeared post-Franco, and in a cultural context profoundly changed by the Movida. Both have published around 150 books of international Crime Fiction, the majority of them considered classics of the genre. While  Etiqueta Negra is a series launched by a Madrid publisher, Jucar, Club del Misterio belongs to a Barcelona-based publisher,  Bruguera.

But the most striking difference is their respective scope. The Madrid publisher puts the emphasis on selection and distinction. There are fewer authors, representing fewer countries, and a distinctive branch within the crime genre, the noir novel. On the contrary, the Barcelona series favours diversity : different subgenres, different authors, different countries.  It is remarkable that the author most published in this series is Italian (Scerbanenco). Rather than American (or Spanish as is at the time the pattern elsewhere, when only local authors seem capable of resisting the American -and to an extent English- dominance).

Historically as well, the books published belong to different epochs. In their contrasts, the two series give an interesting account on two complementary moments in the process of literary selection :  a competition between many varied forms and types of crime fiction, followed by a specialisation in and consolidation of the most successful type.
