In March of 2020, the PHAROS consortium hosted a workshop at the Paul Mellon Centre (partially funded through a grant by the Samuel H. Kress Foundation) focussing on international copyright and photo archive collections.  The workshop included PHAROS institutional members and invited legal and IP experts from the United States, the European Union, and from the United Kingdom. This public report, created by the PHAROS IP Working Group, is the written product of that workshop.
