Date: Wed, 7 Feb 1996 09:15:23 -0500 From: "Winfield, Laurie" Subject: Redlining v. Blacklining Is there any authoritative explanation of the difference between the terms "redlining" and "blacklining" as they apply to documents? In passing, I have supposed that redlining came first, when docs were compared and marked in red by humans. Then software came along that does the same thing, but in black of course, which made the term redlining sound weird when used to describe it, hence perhaps a logical slide to blacklining. But is there anything else behind the lines, as it were?
