I'm revising my book,Opium and the People, for a second edition which will appear next year.I would like the up to date bibliography to be as inclusive as possible.Can members of the network send me a note of references(books and articles) which they think should be in there?(remember that the book is UK focussed-the revised edition will take the story through into the 1920's).I'd much appreciate recommendations for inclusion. Many thanks, Virginia Berridge.
