We present Arecibo time-aligned, total intensity profiles for 46 pulsars overan unusually wide range of radio frequencies and multi-frequency,polarization-angle density diagrams and/or polarization profiles for 58 pulsarspulsars at some or all of the frequencies 50, 111/130, 430 and 1400 MHz. Thefrequency-dependent dispersion delay has been removed In order to align theprofiles for study of their spectral evolution and wherever possible theprofiles of each pulsar are displayed on the same longitude scale. Most of thepulsars within Arecibo's declination range that are sufficiently bright forsuch spectral or single pulse analysis are included in this survey--and thecalibrated pulse sequences are available by web download for further study.
