We have a project, under the aegis of the Nearby Stars (NStars)/Space Interferometry Mission Preparatory Science Program to obtain the spectra, the spectral types, and, where feasible, the basic physical parameters for the 3600 dwarf and giant stars earlier than M0 within 40 parsecs of the Sun. There are 66 B-to-early-F stars among the first 664 stars analyzed in the Northern hemisphere, and 38 of the same among a similar number of Southern hemisphere stars. With these we can start looking at the statistics of Ap, Am, $\lambda$ Boötis, and other A-type stars for a volume-limited sample, and we can find out just how well we know our neighbors. The project's data are available on our website, http://stellar.phys.appstate.eduTo search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
