The many faces of the Archive of the International Ultraviolet Explorer satellite,fferent design philosophies have affected the organization of the archive access and support. Over the past 12 years the linking of computers through networks has had a major impact, not only on the methods used for the maintenance of the IUE Archive itself, but also on its usage and accessibility.

Data Archive Systems for the Hubble Space Telescope,n proposals is an order of magnitude lower than the total proposals. It is therefore essential for an efficient archive facility to be established to allow the world-wide astronomical community to share the tremendous scientific capabilities HST will offer.

The NASA/IPAC Extragalactic Database,s collected in surveys, by the exponential growth in the volume of the technical literature, and by a greater tendency among astronomers to take a multi-spectral approach to the study of astrophysical problems.

Archives of the Isaac Newton Group, La Palma and Westerbork observatories,stitute an archive in this context. Addition of a suitable index or catalogue enabling an outside user to find observations by their parameters would turn the collection of tapes into a proper archive. This chapter deals with the archives of two observatories where archiving was built into the system from the start.
