	M583 Norbert Haider Editorial: MolBank: What Is It Good for? Molbank 2009, 2009(1), M583; doi:10.3390/M583 Received: 14 January 2009 / Published: 15 January 2009 Show/Hide Abstract | Download PDF Full-text (111 KB) Abstract: From time to time, the Publisher and the Editor-in-Chief of MolBank are asked the question: “what is the purpose of publishing a journal like MolBank?” We think that the start of a new year is a good opportunity to make the ideas behind such a journal as clear as possible to our readers, authors and reviewers. In principle, the answer to this question might be boiled down to a single term: “usefulness”. But allow me to go a little bit more into detail. [...]
