I've lately heard mention of two books that are being expunged from existence, because they are instructive for today what they mentioned decades ago. One is "The Road We Are Traveling" by Stuart Chase. You'll easily find mention to it, but not the ability to secure the entire book. The other is "The Managerial Revolution" by James Burnham. You can still find it in various places, but even the used book goes for upwards of $50. Let us all start looking, reading, and posting so as many people possible can know the past so they won't repeat it!
