That is the headline of Rafe Furst‘s blog post here, and that is the subject of his post as well. It is a very entertaining read (hardly surprising, coming from Rafe), especially as he leads up to describing the holy grail of Amazon free grazing: the Minimal Amazon Covering Set, about which Rafe has also set up a Wikipedia page. [ED.: See the comment below re: the removal of the Wikipedia page soon after this post was published.] Here is his description of the enterprise:
A set of keywords that lets you read an entire book for free on Amazon is a covering set (CS). If the number of keywords in a CS is less than or equal to that of all other CSs for the same book, then it is a Minimal Amazon Covering Set (MACS). There may be more than one MACS for any given book. (And yes, someone who is highly skilled at discovering these could be considered a “MACS book pro”).
He also addresses Amazon.com directly, asking just the right question:
Before you look to close this loophole, first check to see [if] your sales numbers are positively or negatively affected. Personally, I find it tedious and not that satisfying to read a book electronically and end up buying the book if I’m at all interested.
I am not convinced that Amazon would even consider this a “loophole,” though I am guessing that publishers might. But maybe I am too skeptical. Remember, I am the guy who wondered whether, if public libraries didn’t already exist, you could ever start one today.

Just search for ‘page 7′ followed by ‘page 8′, etc.
Better yet, buy the book.
Problem is, after x number of page views, you get locked out. Anyone find a way around this? It doesn’t work. I’ve tried on a couple of books…
Looks like Wikipedia took down his page

Is it merely coincidental that MACS is SCAM spelled backwards?
Amazon.com would identify you based on your IP address. So if you’re blocked after a certain number of views you have to change your IP address by 1)on dial-up disconnect and reconnect; 2) on a laptop you can hit another wifi hotspot.
I’m sure you can mask your IP address via certain web pages. I’m not an expert on this matter in any sense, but I do recall that being a safety precaution for paranoid people.
