If I were to set up my own business right now, it would be built around an old-fashioned, mechanical printing press. Minibuk is not doing that, but they are offering people the chance to publish their own books, but real paper books, not e-books. They offer perfect bound, spiral, and saddle-stitched bound books. They are all the size of a small index card, 3 x 5, and intended, from what I can tell of their own promotional materials, as promotional materials themselves. Want people to remember you? Hand them a small book after your talk. It’s an interesting idea.
