In [1,2] we established and discussed the algebra of observables for 2+1 gravity at both the classical and quantum level. Here our treatment broadens and extends previous results to any genus g with a systematic discussion of the centre of the algebra. The reduction of the number of independent observables to 6g-6 (g > 1) is treated in detail with a precise classification for g = 1 and g = 2.
