I have a question about the copyright law with regard to e- publishing.
Lets say, before the e-book era (pre 1990), a publisher obtained license to publish an author's book. The agreement was mute regarding electronic publishing.
Later on, the publisher wants to also publish the same work in electronic format (ebook). Does the publisher has the automatic right to publish the ebook without the authors explicit consent? Or in other words, can the author license to a different publisher to publish the same work in electronic format?
Any legal opinion on this subject will be greatly appreciated.If possible please refer me to a prior case law involving similar situation..
thanks
