ASIt - Atlante Sintattico d'Italia
Our philosophy (in a nutshell):
"Dialectology constitutes a privileged observation point for determining language variation, just because it studies minimally different systems. As such, it is as close as possible to a scientific experiment where variables (intended as differences in grammar) are controlled and few independent factors interfere with the study of a single grammatical property." (from Benincà & Poletto 2007)
