Dymphna Evans, new editor at www.arc-humanities.org (THE APPLIED RESEARCH CENTRE IN THE HUMANITIES AND PRESS LTD) informed me they are developing a digital humanities list on digital humanities.
I don’t know the press but I vouch for Dymphna as editor (she was the editor for Critical Gaming: Interactive History and Virtual Heritage, when she was at Ashgate before it became Routledge).
As well as publishing monographs and collections they are launching a series of short books (20-40,000 words).

The Arc Impact book offers a new route to publication at Arc Humanities Press connecting and looking beyond medieval studies to contemporary humanities research issues. The Arc Impact book offers a route to publish for scholars who have undertaken a specific research project, which does not lend itself to publishing as a traditional journal article or a long-form academic monograph. A more generous word count and faster turnaround time than a journal article allows for rapid publication of results, more scope for case study material and a more immediate impact on the field. The books are typically 20-40,000 words long and priced at an affordable level with open access options.
