Researchers are increasingly tackling complex challenges that cannot always be explored fully through shorter publishing formats. This year, Springer Nature launched Nature Books, bringing one of the world's most recognised scientific brands into book publishing for the first time. In this session, we will discuss the thinking behind the launch, how the Nature brand has been thoughtfully adapted for books, and what it means for authors, readers and the broader publishing landscape. We will explore the opportunities and challenges of extending a trusted brand into a new format while maintaining editorial quality, relevance and a clear value proposition for researchers.
