More than 100, 000 images have been obtained with IUE. The raw and processed data sets are currently stored on an optical disk jukebox maintained by the National Space Sciences Data Center (NSSDC) at Goddard Space Flight Center. The NSSDC archive supports a electronic mail automatic request system from which anyone with a network connection can request data. The project also maintains an online catalog of these observations. This chapter will describe how to find information in the Merged Observing Log (the logs of NASA and VILSPA are merged), and how to request the data.
