Get one of thimblesofplenty's [sic] books _free_.
"thimblesofplenty is a group of friends who also happen to be business people and avid readers. We wanted to keep up with the latest business books but found that time was a factor. So we divided out the work and each of us took a book and summarised it for the others. We though it might be a great idea to share these summaries with you. For a small price and a 3 minute time investment, our summary gives you some of the wisdom from the book, some food for thought and hopefully the impetus to make some time to read the whole book!"
Think of these short books as being like Cliffs Notes, but for business titles.
Of course, we all know that there is not truly a free lunch--someone has to pay a price of some kind for everything. thimblesofplenty requires that you "subscribe" (to get on their mailing list, I suppose) in order to get the freebie, no doubt in hope that you will _buy_ a book, or two or three, after seeing a sample of their work.
Oh, I should mention that their books (some of them, at least) come in English, French, and German.
