  We present the bivariate brightness distribution (BBD) for the 2dF Galaxy
Redshift Survey (2dFGRS) based on a preliminary subsample of 45,000 galaxies.
The BBD is an extension of the galaxy luminosity function incorporating surface
brightness information. It allows the measurement of the local luminosity
density, j_B, and the galaxy luminosity and surface brightness distributions
while accounting for surface brightness selection biases. The recovered 2dFGRS
BBD shows a strong surface brightness-luminosity relation (M_B~2.4\mu_e). The
luminosity-density is dominated by normal galaxies and the luminosity-density
peak lies away from the selection boundaries implying that the 2dFGRS is
complete and that luminous low surface brightness galaxies are rare. The final
value we derive for the local luminosity-density, inclusive of surface
brightness corrections, is: j_B=2.49+/-0.20x10^8 h L_solar Mpc^-3.
Representative Schechter function parameters are: M*=-19.75+/-0.05,
phi*=2.02+/-0.02x10^-2 and alpha=-1.09+/-0.03. Extending the conventional
methodology to incorporate surface brightness selection effects has resulted in
an increase in the luminosity-density of 37%.
