Using both optical color selection and a likelihood method we select 97 candidates over an area of 105 deg$^2$ to a limit of $i_{\\rm AB} < 23.2$, and 7 candidates in the range $23.2 < i_{\\rm AB} < 23.7$ over an area of 18.5 deg$^2$. Spectroscopic observations for 43 candidates were obtained with Gemini, MMT, and LBT, of which 37 are $z>4$ quasars. This sample extends measurements of the quasar luminosity function $\\sim$1.5 mag fainter than our previous work in SDSS Stripe 82.
