Available in PDF, EPUB and Kindle. Book excerpt: The excitation spectrum of the proton is comprised of many broad overlapping resonances, making investigations of these resonances very challenging. Two excellent tools in helping deconvolve the spectrum are eta and eta-prime meson photoproduction from the proton. Since the beginning of this new millennium, much progress has been made in measuring eta and eta-prime meson photoproduction from the proton. These new measurements are largely in the form of differential cross sections that now cover the first and second resonance regions. In addition to differential cross section data, there have been a comparatively smaller number of beam asymmetry measurements for eta photoproduction. However, these beam asymmetries cover the energy range up to only about E_gamma = 1.5 GeV. In this talk, I will present preliminary Jefferson Lab CLAS data on beam asymmetry for both the eta and eta-prime. I will also discuss how the new measurements will be useful in understanding the structure and exci.
