Sábato : historia y apocalypsis / Elisa Calabrese. (OCLC #885797280)

RDA 1.7.3 on punctuation for transcribed elements says to transcribe punctuation as it appears on the source, with an exception to omit punctuation that separates data to be recorded as one element from data to be recorded as a different element.

I consider “Sábato” to be the title proper and “historia y apocalypsis” to be other title information, so the full stop between them is omitted. When encoding our description with ISBD punctuation, these two are separated with a colon. (In ISBD description, a full stop preceding the second element would make it appear more like a dependent title.)
