While every care has been taken in the production of the HELM resources, it is to be expected that some minor revisions may yet be necessary, and the HELM team welcomes feedback from end users.

It is our intention to collate any such information and to provide a final updated set of our materials on CD - ROM to registered project members in September 2006.

Please return to this page regularly if you are using HELM CAA materials, it will be updated on the first of each month.

Contact the project by email: helm@lboro.ac.uk
