I wouldn't wonder about the definitive (the legitimate Who's Who is still in business: http://en.wikipedia.org/wiki/Marquis_Who%27s_Who ) Who's Who showing up in e-mail.
I recall seeing the real Who's Who in America book back in the 70's, at the local public library in the reference section. It was a high quality hardcover volume and very useful in pre-Internet days, at least for high school students needing material for homework papers.
I also remember my boss at a local office supply store in town receiving snail-spam from companies inviting him to join the "prestigeous State Who's Who" and "Retailer's Who's Who" junk postal mail. "Of course, sir, you will certainly want to buy a copy for yourself - a bargain at only $65".
