The Lissadell papers currently occupy 168 PRONI boxes, the contents of some of which have been microfilmed. In addition, five large metal deed boxes (equating to around 30 PRONI boxes) of deeds and leases relating to the Salford and Manchester estate of the Gore-Booth family are covered by the PRONI list but remain physically in Manchester, where they are still of regular, if infrequent, administrative use. Further material, either covered by the list or as yet unexamined by PRONI, remains in family possession, but is destined for PRONI. The largest category is the papers of the late Miss Aideen Gore-Booth, which the owner and depositor has offered to go through with a view to eliminating all that is obviously of no historical significance.
