It's always referred to as "To", "Cc" and "Bcc". I used some email system (back in the early 1980s) that did that. It felt weird even then. I can't remember if it was some CSMail (CSNet) or MH(Rand Mail Handler) version that did it. > Thus, "cc" stems from the old age of literal carbon copies ... That's correct. However: > and "bcc" was seemingly coined when email took over. "Blind Carbon Copies" predated email, but required adding the notation separately, if it was to be added at all. (I'm just old enough to remember using carbon copies myself, but not old enough to know what Standard Office Practice was at that time.) Whether adding a "bcc" notation was common I don't know; it seems it would be easier to leave it off if you made, say, one original and a total of 2 copies, one "blinded". (As your Wikipedia link notes, there was a practical limit to how many carbon copies one could make in the first place.) Chris
