This chapter examines the concept of authorship, as it is understood in copyright law, as well as the first ownership of copyright and the various exceptions to this rule. It begins by discussing the author of a work as defined in the Copyright, Designs and Patents Act 1988 before elaborating on the task of determining who the author of a work is, including difficulties raised by joint authorship. The chapter also looks at exceptions to first ownership, including works created by employees, those governed by Crown copyright or made under the direction or control of Parliament, and commissioned works.
