The concept of authorship is central to how libraries organize their collections. But libraries do not only collect resources created by individuals, they also collect documents issued by organizations. Library catalogers use the concept of a “corporate body” to treat organizations as authors for the purpose of making their documents discoverable to users.

It examines how practices with regard to corporate bodies have changed over time and considers the changes catalogers might expect to see in the future.
