This presentation reviews the progress made since the Photon '97 conference
on the measurements of charmonium states in photon-photon collisions at LE
P. New measurements on chi(c2)-formation are reported by the OPAL and L3 co
llaborations. New results on eta(c) formation, in particular a first measur
ement of the form factor are presented by L3. The DELPHI and L3 experiments
give new limits on eta(c)' formation.
