Società Editrice Internazionale

About

Società Editrice Internazionale (usually shortened as SEI) is an Italian publisher formally instituted in 1908 in Turin. It had however been active since 1859, when it was created by Don Giovanni Bosco, founder of the Salesian Order. After WWII SEI was the leading publisher in school books. Its decline started in the eighties, and in 2018 the Salesiani sold it to Editrice La scuola Brescia. In 2017 it started adding some "educational" board games and web-based games as supplements to its school books. -- summarized from https://it.wikipedia.org/wiki/Societ%C3%A0_Editrice_Internazionale
