At various places I have seen people referring to Segal's papers in CFT as the "standard definition" of the subject. These seem to have become classics in this field. But I can't locate them on the net. I searched on arxiv,spires,Google/Scholar,AMS etc.

The papers I am referring to are (especially the fist one),

G. Segal, The definition of conformal field theory, in: Differential geometrical methods in theoretical physics (Como, 1987), NATO Adv. Sci. Inst. Ser. C Math. Phys. Sci., 250, Kluwer Acad. Publ., Dordrecht, 1988, 165-171

G. Segal, Two-dimensional conformal field theories and modular functors, in: Proceedings of the IXth International Congress on Mathematical Physics, Swansea, 1988, Hilger, Bristol, 1989, 22-37.

G. Segal, The definition of conformal field theory, preprint, 1988; also in: Topology, geometry and quantum field theory, ed. U. Tillmann, London Math. Soc. Lect. Note Ser., Vol. 308. Cambridge University Press, Cambridge, 2004, 421-577.

and on similar lines this paper by Moore and Seiberg

- G. Moore and N. Seiberg, Lectures on RCFT, in: Physics, geometry, and topology (Banff, AB, 1989), ed. H.C. Lee, NATO Adv. Sci. Inst. Ser. B Phys., 238, Plenum, New York, 1990, 263-361.

One possibility is that these are only available in the proceedings mentioned and hence only as books in some library. Are there no online copies of these?
