In the 1980s, a group of great thinkers, authors and communicators penned a series of How To's for honing one's writing skills. The source of these amazing troves of advice was an ad campaign put out by a paper company.

“Today the printed word is more vital than ever," read a box at the bottom of each full-spread advertorial. "Now there is more need than ever for all of us to read better, write better and communicate better. International Paper offers this new series in the hope that, even in a small way, we can help." And sure, International Paper probably also offered that new series in the hopes that, even in a small way, it set them apart from their competitors and inspired you to purchase their paper. But that doesn't diminish the value and insight contained in the following. In fact, these days, you can buy a compilation of all the ads in paperback form.
