Ann, your concerns raise the issue of moral rights as well as legal ownership. It's a fuzzier area of the law, and it varies from country to country, but it covers things like an author's right to proper attribution and to the integrity of the work, even if ownership has passed. In Canada, for example, a sculptor was successful in a lawsuit against a shopping mall that had decorated his statue with Christmas bows.
Here's Wikepedia on moral rights.
In the US, moral rights are stronger in the area of visual arts than written word, but arguably not that strong. But the point is that moral rights and copyright are distinct concepts. Owning a copyright does not necessarily entail being able to do whatever you want with a work.
