The poems and papers are carefully published by Robinson and his group of scholars.
I agree with Shimrod that their work is monumental.
As I am sure Gordon Tyrell did, Oxford Press and the editors should be approached for use of specific material.
The six volumes of poems are not cheap, but few realize the expense involved in putting together, accurately edited, a work of this magnitude.
