These `ebooks´ are incomplete and arbitrarily so....
Or, stated another way, if a trailer is to be considered a "free ebook" then Amazon offers 500,000 "free ebooks." Taking such a position would be an insult to all the volunteers who work so hard to provide *complete* and accurate books to PG. Tracking down and fixing even one missing or damaged page in a book we are trying to get submitted to PG can often easily represent a hard day's work. Rather, let us state clearly what a trailer is: it is an *advertisement*. And people who place advertisements on PG are attempting to *advertise* for free rather than placing their advertisements on a for-pay venue where they belong. Accepting free advertisements on PG would IMHO violate its NFP status, not to mention other obvious problems, like hiding the real value provided by the real [complete] books on the PG website. At the very least PG would need to remove the byline: "We carry high quality items..."
