  We present intrinsic extinction curves for 14 AGNs. The AGNs have reddenings,
E(B-V), of up to 0.36 mag. The majority (13 out of 14) of the extinction curves
are not steep in the UV. Of the seven best determined extinction curves, five
have extinction curves that are as flat as the standard Galactic curve in the
optical and near UV, but flatter in the far UV, and without the 2175 Angstrom
feature. One AGN, B3 0754+394, has a steep SMC-like extinction curve, and
another, Mrk 304, has an LMC-like extinction curve, including a probable 2175
Ang. bump. The remaining seven, lower-quality, extinction curves have overall
shapes that are consistent with an LMC-like shape or a flatter shape. Two have
possible 2175 features, and one might be identical to the Galactic curve. The
flatter curves that predominate in our best determined extinction curves are
not as flat as the Gaskell et al. (2004) extinction curve for radio-loud AGNs.
This suggests that the previous radio-loud extinction curve might be slightly
too flat in the range 4 < 1/lambda < 6.5 inverse microns because of
luminosity-dependent reddening biases in the composite spectra, but further
investigation is needed. We present a parameterized average AGN extinction
curve. Observed variations in the continuum properties of the AGNs are
inconsistent with intrinsic object-to-object variations because observed
differences are least in the far UV where changes in the accretion disk
spectrum should be greatest. We suggest that the steepening of AGN spectra
around Lyman alpha is the result of a small amount of SMC-like dust (E(B-V) ~
0.03). We find the largest object-to-object differences in spectral shape to be
in the Fe II emission of the "small blue bump".
