\begin{enumerate}  \item Description of previous catalog: GZH  Our aim with this proposal is to improve and extend our existing project, Galaxy Zoo: Hubble (GZH) (Willett & Galloway et al., in prep). GZH provides visually classified morphologies for 113,705 galaxies imaged by HST with the ACS camera in multiple surveys (COSMOS, AEGIS, GEMS, and GOODS), the majority of which span a redshift range $0discreet discrete time  intervals out to a lookback time of ~8 Gyr. Gyr, which is necessary to measure the overall evolution of galaxies in this range.      \item Next phase: GZH2, and how it will be improved from GZH
