This panel presentation, to be followed by questions and conversation, features John Mark Ockerbloom, Digital Library Planner at Penn and editor of The Online Books Page and Robert Terrell, Associate General Counsel in Penn's Office of General Counsel. They will discuss finding and making use of public domain material, the legal concept of fair use and the opportunities it provides, the wealth of material openly accessible post 1922 (the usual "safe" cutoff for public domain reuse), and how scholars can further contribute to that wealth by reclaiming and opening access to their own work.This session is part of the Penn Libraries' 2015 Colloquium on Open Access: Open Dialogues on Open Access.
