As Mark says, the place to go is your local museum service. If the York Archaeological Trust aren't making archives available, then try your next nearest museum service. Unless you are thinking of travelling you might be better phoning around local archaeology companies than asking on here. I think most companies would be reluctant to let you take the archive away but they may send you the digitised archive if the museum they deal with require them to create a digitised copy.
