>"Laban notation" "Labanotation"

I tend to agree with you johnjohn - I looked up the UK Laban Centre http://www.laban.org/ and ended up here:

Founded in 1985 and located at the University of Surrey in Guildford, the Labanotation Institute is the European centre for the promotion and development of Labanotation and Laban Movement Analysis. The Labanotation Institute houses an extensive library of labanotated dance scores offers training in Labanotation and Laban Movement Analysis from introductory through to professional level (including the granting of a Professional Diploma) reconstructs and notates works in Labanotation provides a registry of professional notators, liaises with other organisations and institutions in the provision of resources for the teaching of Labanotation and dance maintains links with Labanotation centres world-wide and publishes a newsletter (Action! Recording!) and a technical journal (The Labanotator) discussing the developments in the field.
