Copyright clearance is an increasingly complex and expensive impediment to the digitization and reuse of information. Clearing copyright issues in a reliable and cost-effective manner for works created in the last 100 years can involve establishing complex provenance chains for the works, their copyrights, and their licenses. This paper gives an overview of some of the practical provenance-related issues and challenges in clearing copyrights at large scale, and discusses efforts to more efficiently gather and share information and its copyright provenance.
