Hello A big "thank you" to everyone who responded to my previous request - a huge number of responses with fantastic links and advice. A couple of people have asked if I would mind sending on any emails I receive - if you responded but would prefer that I didn't share the information you sent would you drop me a quick email to that effect please? Many thanks again for all your help, Carol Hallesy Librarian Health Improvement Library Law House Airdrie Road Carluke ML8 5EP
