[Electronic Information for Libraries] On the occasion of World Intellectual Property Day 2020, EIFL worked with leading global cultural heritage organizations in drafting an open letter calling on the World Intellectual Property Organization (WIPO) to take urgent action to help save our cultural heritage. The theme of World IP Day 2020 is ‘Innovate for a Green Future’. This is a welcome goal, but we must not forget the threat to the world's cultural heritage posed by the disastrous effects of climate change, and aggravated by the lack of appropriate copyright legislation supporting the institutions that preserve our common knowledge and heritage.
