My father scanned me this article from Friday's HaAretz about a trove of Genizah fragments that were found by accident in Geneva. Sounds interesting - apparently there are fragments of Talmudic and Geonic works. I'm trying to find out more information.
Update: Apparently the fragments have been in Geneva for more than a century, but no-one noticed them until just a few months ago. They were bought from a papyrologist who visited Cairo in 1896. The contents have not yet been properly reproduced, but Prof. Rosenthal says that there are some significant finds there, including Geonic responsa. The page showed in the newspaper is apparently liturgical, with words from the wedding ritual in it, but its nature is still unclear.
As noted by DafKesher, David Rosenthal published a piece in the literary supplement of Ha-Aretz about the Geneva fragments, which is supposed to be the first of a series. As he mentions, Prof. Sussman was on his way to see the fragments when he became sick. The title of the article is based on a blessing over wine discussed by Naftali Weider in Sinai 20 (1957), pp. 43-48. The blessing is discussed in a Geonic responsum which was known from different sources, but has now been found in full.
He also describes a Massoretic work written by "Rabbi Shmuel, from the mouth of my teacher and master, Moshe ben David ben Yaakov ben Naftali" - this being Ben Naftali of massoretic fame.
Further update: as noted by anonymous, Rosenthal published the second installment of his review. With a photo of a palimpsest (Yahalom and Sokoloff published an article in the 70s about the twenty or so known palimpests in the Genizah, all of which were Jewish texts written over earlier Greek texts, and several of them, like the Geneva one, were Greek biblical translations. Danzig found a palimpsest where both texts are Jewish) and a get from 1148.
