You have until the month of August to download for free Volume 1 of the 20-Volume "Best of Inventors' Digest." (Yes, kids, there still is content for which you have to pay.) The offer is part of the celebration of National Inventors Month (don't tell me that the month is halfway over and you haven't figured out what you're doing to celebrate yet? I'd start by going to Aspen.) Volume 1 opens with Inventors' Digest's First Ten Commandments of Invention. I like # 1:

1. Stay away from invention marketing companies that advertise on radio and late night TV. They’re out to fatten their wallets and empty yours!!! (Remember to ALWAYS ask for references!)

(Tip of the hat to Bill Heinze and his I/P Updates.)
