The document discusses the Astrophysics Data System (ADS), which was established in 1987 to provide access to astronomical data and bibliographic metadata. Over time, ADS expanded to include a full-text archive and became the primary resource for astronomers and astrophysicists. It currently indexes over 15 years of literature and sees high usage rates, with 74% of its traffic coming from Google. The presentation outlines ADS's history and development, current usage, and plans for future improvements to better serve the astronomy community.

‣ Established in 1987 (before the WWW!) as a portal for accessing
astronomical data and bibliographic metadata
‣ Was structured in 1994 to become an A&I service for astronomers
and astrophysicists, with a full-text archive
‣ Has 100% penetration in the astronomical community, with take-up
in other areas of space sciences, engineering and physics
