If you are not familiar with EThOS it is a British service providing dissertations from a number of institutions. When I first heard about it in March I requested copies of all the listed dissertations on Galatians. Unfortunately, I was notified today that one of them will not be available because the university has run out of funding for digitising dissertations. For the low low price of £40 I can still order it but the days of free seem to be over for at least one school. If you are interested feel free to drop some money on this one:
