This is an area I have mentioned a number of times on this site. Having worked withing music management and promotion, it has always puzzled me why the 'DIY' independent approach is perfectly accepted in music and to some degree in the art world, frowned upon in the book publishing word. I wonder if it is because the music business has always been seen as in someways something subversive, like a vehicle to challenge authority, whereas, the publishing industry is seen far more as a tradition corporate entity.
