It’s hit a new high. I see & hear & about 100 times the talk of self publishing books, and books on demand than even 6 months ago. (Later: checked out my hunch) And I buy self published books! Got the sample of this one, will buy it if I like it.
Kim Hill has a discussion with Kate De Goldie & Laura Kroetch on ebooks, (not much on self publishing though).
How to publish on Kindle:
The new Apple book Authoring initiative on iPad ( beautiful but locked down and sinister) Apple iBook Author
The rather wonderful LuLu. Heres one where I bought both the book AND the digital edition: Sociodrama
I’ve just bought a swag of Moreno books that have been republished from through Lulu as well: The First psychodramatic Family
