I'm in the process of deciding on a classification scheme for our new library at Wythenshawe Hospital. Wyth Library uses NLM and Withington uses Dewey. We are a multidiscipliary service. I keep changing my mind between the two. Has anyone got any thoughts about which system I should go for, or give me any advice if you have tackled this problem before?
