None of those models are any different from the model in the U.S. Libraries are already allowed to scan copyrighted works for the purpose of preservation. Google also makes many copyrighted works available from authors who did not request to be removed from their registry. Some orphan works can also be seen at computers at libraries with the same restrictions applying to some of the countries in the article. There has also been discussion in congress over (probably not recently though) making academic journals that receive tax payer dollars available to the public without a subscription fee. There is also the creative commons organization, which issues cc licenses that allows artists to reserve only some of their rights (for instance, a creative commons attribution license allows people to freely copy and distribute the artists work as long as the creator gets credit).
