due to the constrained nature of this novel, each work of translation is actually a re-writing of the book itself. for instance, the choice of lipogrammed letter depends on its frequency of usage. the spanish version (lipogram on a) [see cover] was written by various translating teams (including the german translator of la disparition) and their students over the course of ten years. papers have been written about this process.
la disparition is then, the quintessential untranslatable novel and each of its versions are beautiful reminders (and fetishes) of it.
i have never read la disparition nor any of its translations.
