  We present infrared and millimeter observations of Barnard 335, the
prototypical isolated Bok globule with an embedded protostar. Using Spitzer
data we measure the source luminosity accurately; we also constrain the density
profile of the innermost globule material near the protostar using the
observation of an 8.0 um shadow. HHT observations of 12CO 2 --> 1 confirm the
detection of a flattened molecular core with diameter ~10000 AU and the same
orientation as the circumstellar disk (~100 to 200 AU in diameter). This
structure is probably the same as that generating the 8.0 um shadow and is
expected from theoretical simulations of collapsing embedded protostars. We
estimate the mass of the protostar to be only ~5% of the mass of the parent
globule.
