COMMISION 5. DOCUMENTATION AND ASTRONOMICAL DATA PRESIDENT: W.D. Heintz VICE-PRESIDENT: G.A. Wilkins ORGANIZING COMMITTEE: B. Bauck, J. Kleczek, Pl Lantos, S. Mitton, J.-C. Pecker, L. Schmadel, I. Shcherbina-Samojlova The range of activities of Commission 5 has considerably broadened over the last decade, compared with its originally bibliographical emphasis. This fact is also reflected in the new name of this Commission as adopted at the Montreal con- ference. The increased production of astronomical data, the growing role of data centers in the organisation and retrieval of information, as well as the editori- al and bibliographic processing of the large number of primary papers have indi- cated the need for new and more efficient coordinative guidelines. Several docu- ments have been published and are under consideration, or are in preparation, for the agenda at the IAU General Assembly in 1982. [4 non-relevant paragraphs omitted.] The following Progress Reports (in continuation of those in IAU Trans. XVII A, pt.1, p.7) have been received. Working Group on Astronomical Data (Report for the period 1979-81 by B. Hauck): The main activity of our WG was devoted to trying to centralize the informa- tion concerning the astronomical plate vaults. An inquiry of a large number of observatories revealed that the majority of people concerned are in favour of such centralisation. The CDS at Strasbourg has agreed to act as centralizer. Details concerning this action will be published in the proceedings of the IAU Colloquium No. 64. Our WG was also interested in the Flexible Image Transport System (FITS, see D.C. Wells et al., A.A.Suppl. 44, 363; E.W. Greisen and R.H. Harten, A.A.Suppl. 44, 371, 1981) and will support this very valuable solution for the exchange of data. During the period covered by this report we have seen the development of ast- ronomical data networks: STARLINK in the U.K., ASTRONET in Italy, and another one in Japan. The development of stellar data centers is encouraging and the fact of having such centers in France, USA, USSR, Japan and the DDR facilitates the access to astronomical data. The most important developments in this field are definitely the Catalogue of Stellar Identification (F.Ochsenbein et al., 1981, A.A.Suppl. 43, 259) at the CDS, Strasbourg, and the Infrared Data Base at the GSFC, Greenbelt, Maryland (see D.Schmitz et al., 1981, Astron.Data Center Bull. 1, 94). CODATA's scientific conference was held at Kyoto (October 8-11, 1980). The proceedings of this conference are now available (Ph.Glaeser, Data for Science and Technology, Pergamon Press, 1981).
