Thanks. I wasn't aware of that.

> Publisher vs Distributor?

Whatever these roles imply in this particular case, it may seem that Digita was the sole publisher while there were various national distributors. But taking "in English" into account, it may as well be that regarding TurboCalc, Digita was for the English speaking countries what Schatztruhe was for Germany and NonSoloSoft for Italy, meaning that the terms "publisher" and "distributor" would be interchangeable here.
