The Harvard College Observatory Library collection began in the mid-1800's resulting from the exchange of scholarly works among observatories worldwide. The Smithsonian Astrophysical Observatory Library came about when astronomical material in Washington, D.C. was moved to Cambridge, MA in the late 1950's. In 1975 the two libraries were merged and became the Wolbach Library at the Harvard-Smithsonian Center for Astrophysics.
The SAO/NASA Astrophysics Data System (ADS) is an online database for researchers in Astronomy and Physics, operated by the Smithsonian Astrophysical Observatory under a NASA grant. The ADS is located within the Wolbach Library and the two collaborate on a variety of projects. One such project is the Unified Astronomy Thesaurus.
