Mike Brocken is/was a senior lecturer in creative and performing arts at Liverpool Hope University. The book, The British Folk revival, 1944-2002, came out in 2003, published by Ashgate (usually very expensive books, but this is/was available in paperback.) May still be available. It was based on his PhD thesis. he is a Liverpudlian, went to West derby Comp in the 60s (according to book intro).
As part of the book research, he attempted a full discography of Topic records, which Rod Stradling completed on Musical Traditions website, though Brocken stuck to his incomplete listing.
I may be wrong, but I don't think the book created any waves...
