All the quasars have been detected in the mid-infrared bands of ISOCAM, while no far-infrared detections have been made with ISOPHOT. SEDs (Spectral Energy Distributions) from the UV to far-infrared have been obtained while supplementing ISO observations with photometry in the optical and near-infrared made from the ground within 17 months. The SEDs are compared with the MED (Mean spectral Energy Distributions) of low-redshift quasars with -27<MB←22. It is shown that our far-infrared observations were limited by confusion noise due to crowded sources. Description: File table3 contains the flux of quasars at high-redshift observed with ISO. File table4 contains the magnitude of them observed from the ground. File Summary:
