  Recently Schlegel, Finkbeiner & Davis published an all-sky reddening map
based on the COBE/DIRBE and IRAS/ISSA infrared sky surveys. Using the reddening
map of Baade's Window and sample of 19 low-latitude ($|b|<5\deg$) Galactic
globular clusters I find that the DIRBE/IRAS reddening map overestimates
$E(B-V)$ at low galactic latitudes by a factor of $\sim 1.35$. I also
demonstrate the usefulness of this high resolution map for selecting
low-reddening windows near the Galactic plane.
