From their website:
Wizard’s Tower is a not a traditional publishing company. We do not generally buy new works, but rather concentrate on making out-of-print works available once more as e-books, and helping other small presses exploit the e-book market. Our interests are solely in the areas of science fiction, fantasy and related markets.
We are interested in hearing from you if:
You are an author with out-of-print works you would like to make available as e-books
You own a small press and are interested in getting into the e-book market but feel you need help
You manage an author’s estate and are interested in making that author’s work available as e-books
We will also publish a small number of limited-print-run anthologies with a view to encouraging diversity in the science fiction and fantasy field. Preference will be given to the following:
Local author anthologies (particularly from South-West England or Wales)
Anthologies of work by women writers
Anthologies of work by LGBT writers
Anthologies of work by people from specific cultural or ethnic backgrounds
Anthologies of work translated into English from other languages
We are interested in hearing from anthology editors in these areas.
