\textit{\textbf{K.W. Willett et al.}}  The Galaxy Zoo project uses crowdsourced visual classifications to create robust, large catalogs of detailed galaxy morphology. We present initial results for the Galaxy Zoo: Hubble dataset, which includes 169,944 images of galaxies selected from the AEGIS, COSMOS, GEMS, and GOODS surveys. The galaxies span a redshift range of $0We also present preliminary results analyzing disk sub-structure as a function of redshift.  All the above data will be included in the upcoming release of the full Galaxy Zoo: Hubble catalog.
