many thanks for your reply's guys and for the very warm welcome you have given me.
There are many archives online now a days and I have spent many hours trolling through lists of mostly Shakespeare plays. Other sources for material come in the shape of forums such as your own good self's. Just to expand on my search here is a web site that explains the sort of thing that I am after
http://www.missing-episodes.com/ it makes quite sad reading that so much of our culture and history has been lost. many thanks again.
