Title:  High-resolution spectroscopy of Herbig Ae/Be Stars

In a multi-year, high-resolution optical spectroscopic survey, we have observed ~60 Herbig Ae/Be stars, the higher mass counterparts of T Tauri Stars (TTS). We present here portions of our spectral atlas, as well as a detailed look at the ~30 multi-epoch observations obtained during this program. We discuss our sample in the context of pre-main sequence evolution as a function of stellar mass; specifically, how our present picture of magnetospheric accretion for Herbig Ae/Be stars is diverging from the paradigm envisaged for TTS.
