The digital era has brought a change to the information world. Digital information is collected in repositories, is described with metadata and is disseminated through digital libraries. But many issues are in debate, even what in fact constitutes a digital object, how to create, store and handle complex digital objects and how to preserve the digital information in the long run. Digital objects are used more extensively than traditional ones, which affect their cost and pricing. The enforcing of the copyright is more imperative, while at the same time copies have to be created for technical reasons alone. It is difficult to distinguish and prevent unauthorized copying and plagiarism, there are many more parties that may be responsible for bad use and the fair use appears in different ways. There are unusually many orphan works and many digital objects have unclear terms of usage or are often offered under open access, such as Creative Commons licenses. Libraries have a new role in this context, which involves using, creating and sharing digital libraries.
