I’ve recently published a review in BJET of a book about Action Research aimed at doctoral students. I did find Willis & Edwards’ book useful where the SAGE handbook can be a bit intimidating… Amazon are selling it for about £40. Sadly, it’s not in the Lancaster library (at the moment! – but I must say I’ve found the library refreshingly receptive to recommendations in the past).
This sort of highlights the significant perk of getting into book reviewing… You get to keep the book! I know that’s stating the obvious, but I do enjoy a real paper book, on a substantial topic, ‘to have and to hold’ (I do think e-books are very useful, not least for the capacity to search the full text).
