Have a look at my newly opened home page:
http://www.stir.ac.uk/epd/higgins.htm
At the moment the only relevant document there is a list of RP homophones
extracted from the Advanced Learners Dictionary. I am planning to place on
it during the semester the products of the concordance searches we carry
out as exercises on the course I teach here at Stirling, starting next week
with 'on my own' versus 'by myself'.
