[o] ADS Abstract Service Provided by the Astrophysics Data System at the CfA to search astronomy periodical abstracts
(Mirror sites at Nottingham and at Strasbourg).

o Astroweb Astroweb is a collection of pointers to astronomy-related information available on the Internet, maintained by the AstroWeb Consortium.


o Cambridge Astronomical Survey Unit The APM facility, Carlsberg Meridian Telescope, and wide-field astronomy projects.


o CADC: the Canadian Astronomy Data Centre A major international centre for data archives.
o DSS: the Digitized Sky Survey The Digitized Sky Survey, at CADC or LEDAS.


o Double Star Library Catalogues and news of all types of binary and multiple systems, organized under the auspices of IAU Commission 26.


o ESAC Science Data Centre Provides links to the data archives of all ESA science missions.


o ESIS: the European Space Information System The ESIS project is a service to the Space Science community to provide access to scientific data, including catalogues, images and spectra from a wide range of ESA/non-ESA space missions. The ESIS Bibliographical Database combines the NASA Abstracts archive with SIMBAD references. A form-based interface allows you to search for bibliographic references in various ways.


o HEASARC The High-Energy Astrophysics Science Archive Research Center


o HISTORY OF MATHEMATICS - Astronomy Section (maintained by St Andrews University)

o ING Data archives of the Isaac Newton Group of telescopes.


o IRSA: the InfraRed Science Archive IRSA provides archiving and 'data mining' of infrared-astronomy (and submillimetre) catalogues, including IRAS, ISO, Spitzer (SIRTF), and 2MASS.


o LEDAS: the LEicester Database and Archive Service LEDAS provides an on-line astronomical database service, and access to archival data from high-energy astrophysics missions.


o MAST: the Multimission Archive at Space Telescope MAST supports a variety of astronomical data archives, with the primary focus on scientifically related data sets in the optical, ultraviolet, and near-infrared parts of the spectrum, including HST, IUE, EUVE, ASTRO & ROSAT. 


o Meetings A comprehensive hypertext list of international meetings, maintained by the CFHT library.
o Membership Directories:


oThe National Cataloguing Unit Catalogues and archives papers of "contemporary" scientists, including some RAS luminaries, such as Sir Harold Jeffreys and Keith Runcorn.


 o NED The NASA/IPAC Extragalactic Database, including cross-identifications, positions, redshifts and basic data, plus bibliographic references.


o NIST Physical Reference Data Includes physical constants, atomic and molecular spectroscopic data.


o NSSDC NASA's National Space Science Data Center; includes the permanent archive for most NASA astrophysics data.


o SIMBAD Astronomical Database SIMBAD provides basic data, cross-identifications and bibliography for astronomical objects beyond the Solar System.


o SkyView SkyView is a virtual observatory on the internet. It can be used to generate images of the sky at wavelengths in all regimes from radio to gamma-ray using various sky surveys as input.
