The Royal Society Library conducted a study of its Fellows' use of the library. It found that while most Fellows say their usage hasn't changed, more report that it has declined than increased. Fellows access information through their own institutions and online instead of the library. However, some still use it for rare resources and as a quiet workspace. To better serve Fellows, the library aims to extend hours, provide online access, and publicize its services and collections. The study highlights how learned society libraries can adapt to modern research habits while maintaining their value to Fellows.
