Astrophysics Data System
The Astrophysics Data System ( ADS ; German " Astrophysics Data System " ) is one of the NASA -funded database for literature in the field of astronomy and astrophysics . Publications from physics and geophysics as well as electronic preprints of the ArXiv system are also included.
The ADS is the most comprehensive literature collection in the field of astronomy. Information such as title, authors, summaries (abstract) and citation frequencies are freely accessible. Many older specialist publications are fully accessible, while newer publications are usually only available to paying subscribers to the relevant publications via links.
In April 2018, 2.30 million data sets from astronomy / astrophysics, 9.17 million from physics and 1.37 million ArXiv data sets were available.
The identifier used by the ADS to uniquely identify data sets, the so-called bibcode , is widely used in astronomy and astrophysics for referencing specialist literature.
The user interface is characterized by a wide range of functions. Due to the comparatively spartan and simple formatting of the web pages, the display works with all browsers. Efficient access is also possible with slow data lines.
