Zoetic Press is a relatively new publishing company that produces interactive e-books using an app called “Lithomobilus.” It is at present only available only on iOS, but an Android version is coming soon. Their projects involve publishing ebooks that feature classic, public-domain novels alongside contemporary responses to them, and they have a literary magazine featuring books reviews as well. The table of contents for each work is a straight line down the middle of the screen displaying novel chapters to the left and contemporary responses to the right, chapter by chapter.
At present they have editions of Frankenstein, Alice in Wonderland, The Strangely-Brown Episode, Grimm’s Fairy Tales, The Wizard of Oz, Bulfinch’s Mythology, and The King in Yellow, plus one “Unbound” edition that is organized around an initial submission by a current writer followed up by response works. More are in the works.
