Both Print and Ebook versions of Steven Disney's "Perceptions of the Mind" are now currently available in the Lulu outlet. The Ebook is pending for Barnes & Noble and the iBookstore. I am also working on a version for Kindle. The Kindle release will take longer though. I am not sure about releasing on Smashwords, but might, so that it is available to those that don't want to go through Lulu or B&N.
Once I have more time, the other available titles, both from myself and from Steven, will eventually make their way to Kindle. However, homework first before I press on more with conversions and uploads.
