We present spectrophotometric data from 0.4 to 4.2 micron for bright, northern sky, Be stars and several other massive early-type stars. Our goal is to use these data with our ongoing, high angular resolution, interferometric survey to model the gas density structure and sky orientation of the circumstellar envelope surrounding
these stars. We also present a montage of the Halpha and near-infrared emission lines that form in Be star disks. We find that a simplified measurement of the IR excess flux appears to be correlated with
the strength of emission lines from high level transitions of hydrogen. This suggests that the near-IR continuum
and upper level line fluxes both form close to the central star, in the inner part of the circumstellar disk.
