Our open access review on the evolution and chemistry of protoplanetary disks is online at the site of Springer Link. \”The Gas Disk: Evolution and Chemistry\” has been the result of collective effort with a number of collaborators from the Department of Astrophysics at the University of Vienna. It is a great reward to see that just a month after it came online, it has a more than 130 direct downloads from the publisher\’s site.
