\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 $0  The large number of galaxies in this catalog allow the populations of morphological classes of galaxies to be analyzed locally \emph{and} at discrete time intervals out to These data enable  a lookback time wide range  of ~8 Gyr, which is necessary studies related  tomeasure  the overall morphological  evolution of galaxies in this range. galaxies, several of which have already been conducted using GZH data, including bar fraction with redshift \citet{Cheung2013,Melvin2015} and passive disk fraction with redshift \citet{poster}.      \item Next phase: GZH2, and how it will be improved from GZH
