The formation of charmonium states in photon-photon collisions at LEP

This presentation reviews the progress made since the Photon '97 conference on the measurements of charmonium states in photon-photon collisions at LEP. New measurements on χc2-formation are reported by the OPAL and L3 collaborations. New results on ηc formation, in particular a first measurement of the form factor are presented by L3. The DELPHI and L3 experiments give new limits on ηc′ formation.
