terms of answering the question of the form of the reddening. Nevertheless, we have shown that the reddening that is observed in our BALQSO sample is certainly [*consistent*]{} with SMC-like dust as suggested by previous authors. Furthermore, at least some contribution from reddening is favored for LoBALs, as seen by the $\chi^2$ of the fits in Figures \[fig:fig4\] and \[fig:fig5\] and our analysis in § \[sec:colortrends\].

If BALQSOs and nonBALQSOs have the same intrinsic spectral index distribution and BALQSOs are reddened by SMC-like dust, then the average reddening for HiBALs is $E(B-V)=0.023$ and for LoBALs is $E(B-V)=0.077$ (as compared to the EDR composite spectrum, which is reddened by $E(B-V)\sim0.004$ as compared to the nonBALQSO composite). These numbers can be compared to & [Foltz]{} (1992) and (2001) who each applied an SMC reddening law and found that $E_{Lo} - E_{Hi} \sim 0.1$ was needed to account for flux deficits in LoBALs as compared to HiBALs. Our results suggest a smaller differential reddening between the HiBALs and LoBALs. This small difference between our results and previous results may be related to the fact that the SDSS EDR BALQSO catalog includes a much larger fraction of BALQSOs with smaller balnicity indices than the
