Search the SAO/NASA Astrophysics Data System

The SAO/NASA Astrophysics Data System (ADS) is a Digital Library portal for researchers in Astronomy and Physics, operated by the Smithsonian Astrophysical Observatory (SAO) under a NASA grant. The ADS maintains three bibliographic databases containing more than 8.6 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints.

In order to search the ADS from Tellico, you can use a script that I just uploaded to kde-files.org. Download the script, and then add a new external data source in Tellico with the settings as shown below. Change the location to wherever you saved the script.

The search returns results in Bibtex format, which means that many of the values are bracketed for inclusion in Latex documents. Tellico does strip those brackets when viewing the entries, but they are saved in the data.
