For more than a decade proponents of digital publishing have held out the promise of production and distribution efficiencies that would alter the future course of publishing. Certainly in the other media, digital formats and digital delivery have created an upheaval that would be characterized as nothing short of disruptive. It could also be argued that digital publishing would have achieved meaningful traction long ago there had been fewer offerings and greater focus in the marketplace - many publishers complain that the space is already too crowded with a confusing array of formats, devices and platforms. Certainly there are more output options today for publishers than any other media.

The following is considered a conservative list of viable options:

1. Kindle (ePub through mobiPocket)
2. Sony Reader (ePub through Adobe Digital Editions and BBeB)
3. iPad (Apple)
4. mobiPocket (for smart phones and mobile phones)
5. iPhone (Stanza)
6. Adobe Digital Editions
7. PDF (image)
8. PDF (P.O.D)
9. PDF (streaming -ebrary library solution)
10. PDF (Searchability -Amazon, Google)
11. HTML (web browser applications)
12. Palm OS
