The document discusses sustainability and project lifecycles in relation to Europeana digital library projects. It outlines three scenarios for what may happen when projects end: 1) the project ends completely, 2) a follow up project is launched, or 3) an aggregator takes over the project's functions. The key points are: - Sustainability means a project's results continue beyond its end through ongoing use and exploitation. - Europeana developed a Project Shift Plan to help preserve work from ending projects and ensure a smooth transition. - The Plan involves surveys, collaboration between projects and Europeana, and outlining responsibilities under the three scenarios. - Projects ending within 12 months should evaluate which scenario applies and contact Europe
