bq. It says that “a group of law students search the World Wide Web continuously for new sites and maintains the database in proper shape.” You can start with just about any country and then drill down to the main legal resources.
It is worth searching. I immediately found the Südtiroler Bürgernetz (having been translating some stuff from that area) and its law links. But there are also 182 taxation links. I have not spent long enough here to understand the organization of the site, but it looks as if there are internal links so you can reach links by more than one path.
