The properties of pseudoscalars and glueballs are discussed. In the framework of the MIT bag model mass corrections to second order are calculated, which for ..cap alpha../sub s/ = 1.58 solve the U(1) problem. No quantitative predictions for glueball masses can be made. Glueballs and pseudoscalars mix strongly. SU(3)/sub flavor/ is not a good symmetry. A heavy quark mass expansion is used to calculate the radiative decay of vector mesons into pseudoscalars. The conclusion is reached that psi radiative decay is the best source for light glueballs. The glueball candidates are reviewed. The predictions of a general quark model show that the iota(1440) cannot be explained as a quark-antiquark state. Thus, the most likely interpretation for the iota is a glueball.
