The online edition of the Nature Publishing Group catalogue has been given a thorough overhaul in its design, navigation and behind-the-scenes authoring tools. The site holds all the information from the printed catalogue, including journals’ aims and scopes; impact factors and rankings; launch dates; editors; and society owners. The site can be searched by keyword and subject-related journals, plus a full A-Z list. Visitors can also order a printed catalogue or view as a (rather large) PDF.
