  We present a mid-infrared analysis of 35 quasars with spectroscopic redshifts
selected from the Spitzer Wide-area InfraRed Extragalactic Survey (SWIRE). We
discuss their optical and mid-infrared (MIR) colors, and show that these
quasars occupy well defined regions in MIR color-color space. We examine the
issue of type-I AGN candidate selection in detail and propose new selection
methods based on mid-IR colors. The available multi-band data allows us to
construct two new, well-sampled quasar templates, covering wavelengths from the
ultraviolet to the MIR.
