The revised Google (NSDQ: GOOG) Book settlement scales back the countries the agreement covers and promises new protections for potential rights-holders and authors (Read in detail what those changes entail here). That, however, doesn’t seem to have placated two key interest groups:

—Justice Department: The DOJ was consulted repeatedly in the drafting of the new settlement. However, it “remains concerned that the fact the settlement gives Google immunity from lawsuits related to orphan works may be anticompetitive,” the WSJ reports, citing people familiar with the matter.

—Competitors: Less surprisingly, Google’s rivals remain up in arms. The Open Book Alliance—which is made up of Amazon (NSDQ: AMZN), Microsoft (NSDQ: MSFT), Yahoo (NSDQ: YHOO), and some other entities—put out a statement saying the changes were too minor: “By performing surgical nip and tuck, (the parties) are attempting to distract people from their continued efforts to establish a monopoly over digital content access and distribution; usurp Congress’s role in setting copyright policy; lock writers into their unsought registry, stripping them of their individual contract rights; put library budgets and patron privacy at risk; and establish a dangerous precedent by abusing the class action process.”

No happy words there from a group that says it does not want to have one entity controlling the distribution of what it is calling “the world’s largest digital database of books.”

Next steps? Google says a hearing will likely be held in early 2010. Before then, expect a slew of new filings from interested parties, including the DOJ.
