Which plaintext languages to try?

[Mauro]

Venetian is a language separate from Italian with many local varieties. Its exact place within the Romance language family remains somewhat controversial. Both Ethnologue and Glottolog group it in the Gallo-Italian branch (and thus closer to French and Emilian-Romagnol than to Italian). [8][7] Devoto, Avolio and Ursini reject this classification,[15][16][17] and Tagliavini assigns it to the Italo-Dalmatian branch of Romance. [18]

Can you post the links to the references in square brackets, please (or a link to the original quote)? I'm interested in reading which arguments Devoto etc. used to reject Venetian from the Gallo-Italic branch. I side with Ehtnologue etc. on this, but reading and evaluating the opposing arguments would be nice.
