It is unclear if the letters are in their original order. The letters were deposited already arranged in to files for each sender, and some appear to be those addressed directly to Irene. However there is also correspondence between the senders and the Withymead Centre/other staff. The matters discussed in the latter letters are sometimes about Irene and her conduct, suggesting the correspondence was not originally sent to, viewed by or answered/filed by her. It seems likely that there were originally at least two distinct sets of letters - Withymead Centre correspondence, and Irene's own set of correspondence. Perhaps the letters were rearranged into sender files at a later date. Either by Irene (as some letters appear to have later been annotated by her when she had sight of them) such as when Irene came to possess the Withymead papers, or by a third party after Irene's death. There are also what appear to be the original (not photocopies) of Irene's outgoing letters, it is unclear how they were returned (rather than retained by the receiver) or if Irene hand copied them out before sending.
