Volume XX - in two substantial volumes - listing several hundred manuscripts 
has at last been published. Work on Volume XX has been progressing steadily
since the year 2000, when I discovered to my horror that all the files which I had
accumulated since 1960 had been lost in transit from Suffolk to London. I have
had, in effect, to retrace the research of almost forty years. Not, in fact, possible.
However, over two thousand entries have been recovered, and I hope that, notwiths- tanding the loss of records and photographs of several hundred items in some 120 libraries, the corpus of recovered entries will prove fruitful for researchers in English language history.
