We recently proposed the equivalent width (EW) of the narrow [OIII]5007{\AA}emission line as an orientation indicator for active galactic nuclei. We testedthis method on about $12,300$ optically selected broad line quasars from theSDSS 7th Data Release at redshift $z < 0.8$ and with full width at half-maximumvalues of broad emission lines (H$\alpha$, H$\beta$, and MgII) larger than$2000$ km/s. We now examine their spectral energy distributions (SEDs) usingbroad band photometry from the near-infrared to the ultraviolet to look forvariations in the overall shape as a function of the EW[OIII]. We find thatquasars with low EW[OIII] values (close to face-on position) have flatternear-infrared SEDs with respect to sources with high EW[OIII] values (almostedge-on). Moreover, quasars with high EW[OIII] values show a factor of $\sim 2$lower emission in the UV to quasars with low EW[OIII] values. Our findingsindicate that the torus is clumpy and, on average, co-axial with the accretiondisc and broad line region, in agreement with the most recent theoreticalmodels for the obscuring torus.
