The present status of experimental searches for glueballs is reviewed. A critical examination is made of the criteria used in the identification of glueballs. It is concluded that the mixing of glueball states with normal qq states deprives us so far of any 'smoking guns', and at least two states, f

β¦ Synopsis
I briefly review lattice QCD calculations that study the 0 ++ glueball and discuss implications for light flavour singlet 0 ++ mesons.

The f0(1500) is identified in three glueball favoured production mechanisms: pl6 annihilation, ~b --~ 7f0 and Central Production. The production rate for glueballs in Β’ ~ 7G has been quantified and the f0( 1500) is found to be consistent with a glueball -q~ mixture. We illustrate a remarlmble proper
For some experimental guidelines of the next millennium, I review the determinations of the masses, decays and mixings of the gluonia, scalar and hybrid mesons from QCD spectral sum rules and low-energy theorems, and compare them with the lattice.
