The following document is particularly important and required reading for any person studying the relationship between the Channel Islands and the United Kingdom.  It is the UK government's view of that relationship and the practical details of how it is managed.  Given the source of the document it is necessarily of some authority on the subject, although far from being the last word:  http://www.dca.gov.uk/constitution/crown/govguide.htm
