The National Trust, the Council for Environmental Education and the Government are launching a national code of practice for companies and organisations who are involved in producing dev-elopment education resources, at the Education Show. It was widely felt that more should be done to raise the standards for consumers and educationists as well as co-ordinating production and eliminating unnecessary duplication, said the National Trust. The full code or a shorter version can be obtained by writing to DETR Free Literature, PO Box 236, Wetherby LS23 7NB. Tel: 0870 122 6236. www.detr.gov.uk. Stand M42
