The main academic full-text databases are open archives or link-resolution services, although others operate under different models such as mirroring or hybrid publishers. Such services typically provide access to full text and full-text search, but also metadata about items for which no full text is available.
Caldwell catalogue. Montage of Caldwell Catalogue objects. The Caldwell catalogue is an astronomical catalogue of 109 star clusters, nebulae, and galaxies for observation by amateur astronomers. The list was compiled by Patrick Moore as a complement to the Messier catalogue. [ 1]
The GC contained 5,079 entries. Later, a complementary edition of the catalog was published posthumously as the General Catalogue of 10,300 Multiple and Double Stars. The small "h" followed with the catalogue entry number represented the item. [4] In 1878, John Louis Emil Dreyer published a supplement to the General Catalogue. [6]
Gliese published an update as the Catalogue of Nearby Stars in 1969, all known stars to 22 parsecs (72 ly), which catalogued 1,529 stars, [ 2] encoded as Gl NNN.NA (prefix Gl and the entries of twelve years before gained a .0 affix; the more than 500 additional stars were recorded using interspersed 0.1, 0.2 etc. numbering).
