Tradsinger;
"I am currently liaising with the British Library Sound Archive to put my field recordings on line."
We put ours there when Lucy Duran was running the show - it was the British Institute of Recorded Sound then (late 1970s).
Our having done so was the impetus for their expanding what was then a mainly international (largely Asian and African) archive into one that could also cater for British/Irish recordings.
Unfortunately they never got round to putting our recordings on-line. I understand that following the 'Bright Golden Store' project they ran out of money, so ours languishes in a vault somewhere - which is not why we made the effort.
I suggest that if this in not what you want to happen to yours, you discuss with them how accessible they are prepared to make it - I still get extremely frustrated with archives that are 'saved for posterity' rather than made fully available.
Good luck
