The DML workshop’s objectives were to formulate the strategy and goals of a global mathematical digital library and to summarize the current successes and failures of ongoing technologies and related projects. There is already experience with building regional DMLs or building big thematic scientific digital libraries. EuDML project reached it halflife period. While there are already big fulltext digital libraries in some domains like PubMed Central in the biomedical domain, Inspire in high-energy physics, why did not these emerge in other scientific areas? Will EuDML project in mathematics follow their success? Which crucial decisions has to be taken so that the heritage of mathematics would be sustainably at fingertips of scientists? We pose such and other questions, and try to find some answers in papers of this proceedings.
