In the last few days, bookselling giant Amazon.com Inc (NASDAQ: AMZN) has made a few more enemies in the publishing world by forcing the little-known group of print-on-demand (POD) publishers to either submit to using its POD subsidiary, Booksurge, or risk being prohibited from selling on its industry-leading website. No matter the cost and complications of breaking off relationships with other vendors, reformatting books and a host of other problems, Amazon laid down the law, saying convert -- and do it quickly -- or face the consequences.

What's more disconcerting is that an official press release was made public only after smaller publishers like Angela Hoy of Booklocker.com started writing publicly about blackmail-type phone calls from Booksurge representatives. Fearful of losing their businesses literally overnight, many POD publishers such as iUniverse and Lulu have capitulated while strong willed publisher PublishAmerica refused to give in -- and was quickly made an example of when Amazon disabled the buy buttons on their book titles!

As an author selling my own critically-acclaimed POD book An American Hedge Fund on Amazon, outrage has compelled me to write about how unethical and more importantly, monopolistic this all is.
