At the beginning of the INCA Consortium work in 1982, no specific general astrometric catalogue of double and multiple stars was available, and the construction of such a catalogue was therefore undertaken. This project was carried out at the Observatoire Royal de Belgique (Dommanget 1983, 1989), under the name of Catalogue of Components of Double and Multiple Stars (CCDM). The original basis of CCDM is the IDS catalogue (Jeffers et al. 1963) augmented by a number of measurements collected at the US Naval Observatory by Worley and transmitted to the Meudon (later to Nice) and Royal Greenwich Observatories until 1976. For logical reasons, the WDS catalogue (Worley & Douglass 1984) was not used.

The absolute positions in the CCDM have been taken from various sources, but primarily from the CDA Catalogue (Bastian & Lederle 1985, Jahreiß 1989). In addition, it has been complemented during the years 1982-91 by more than 40,000 accurate positions and proper motions for individual components, obtained by mean of specific astrometric observations, organized within the framework of the INCA Consortium Working Group on Double Stars. Numerous institutes participated in these observations: Observatoire Royal de Belgique, Bonn, Bordeaux, Brera and Torino Observatories, Cambridge, La Plata, Leningrad, Lille and München Universities with observations also made at ESO and at La Palma. New data have been included, first into the CCDM and then into the INCA database, after systematic checks of their internal consistency. Some positions are also taken from the GSC Catalogue (Lasker et al. 1990).

The CCDM includes about 63,000 systems, and aims to provide (for each component) accurate positions (better than 1"), proper motions, and cross-identifications with the most important reference and fundamental catalogues.
