The ESO Library develops and maintains two major information resources: the telescope bibliography (telbib), a database of refereed articles that use observational data from ESO facilities, and the library catalogue. In order to provide an optimal viewing experience from a large number of devices, the web interfaces of both tools have been adjusted using the Responsive Web Design (RWD) approach. This assures that users can search and navigate both sites from various screens, including desktop computers, tablets and smartphones, with minimal resizing and scrolling. Please try these resources from your favourite device.
