Five organizations representing E.U. publishers, libraries, rights holders and businesses active in Internet commerce told the European Commission at a hearing on Monday that the proposed U.S. Google book settlement is unacceptable in its present form, because it would lead to "a de facto monopoly" in the emerging digital books market.

"We should not let a single U.S. entity dictate an international model of rights recording," said Peter Brantley of the Internet Archive and Open Book Alliance, one of the five organizations.

Google doesn't expect to win them all over with the two initiatives, but it is having more success winning support for its book digitizing ambitions in Brussels.

The U.S. settlement between Google and U.S. publishers, which is still under scrutiny by a New York court, was the subject of a one-day hearing hosted by the European Commission Monday.

It will be followed Tuesday by a series of one-on-one meetings between Information Commissioner Viviane Reding  and, among others, Dan Clancy, Google's top executive responsible for the Books project.
