Abstract: 
Cross-sections, beam asymmetries, and recoil polarisations for the reactions gamma p -> K (+)Lambda;gamma p -> K (+)Sigma(0), and gamma p -> K-0 Sigma(+) have been measured by the SAPHIR, CLAS, and LEPS Collaborations with high statistics and good angular coverage for centre-of-mass energies between 1.6 and 2.3 GeV. The combined analysis of these data with data from pi and eta photoproduction reveals evidence for new baryon resonances in this energy region. A new P-11 state with mass 1840 MeV and width 140 MeV was observed contributing to most of the fitted reactions. The data demand the presence of two D-13 states at 1875 and, optimistically, at 2170 MeV.
