Jim,
Off the top of my head all of the above list were digitised as a job lot by Andrew King under the heading 'Traditional Music in England Project' c2002. Your recordings as you say were donated much earlier than this and as part of a different project, which is presumably why they are not accessible under the same conditions. If you email Janet Topp-Farjion who occasionally chips in on the Tradsong website she might be able to see that your collection is put into the same availablity as the collections above. Indeed it's something I'd like access to certainly.

Yes Julia, Vic, David et al are based at Aberdeen Univ. working on Carpenter. We occasionally get updates on their work at TSF meetings.

Regarding shanties, there are definitely some in my collection from 2 different singers, one an ex captain and the other an old Cape-Horner.
