Comment on A list of Print-on-demand publishers, self-publishing/”Vanity presses” and other non-traditional publishers for librarians and authors by tnesla

I’ve been trying to find information about the status of H&S Media, which appears to be an “on- demand publishing and digital distribution” company, apparently set up in the UK. H&S seems to specialize in Persian content although language of publication is not limited to Persian and their catalog includes some books n English as well. I’ve come across with a very attractive ‘call for contributions’ for an edited book on contemporary cinema but the name of H&S is involved and I don’t know what to think of it. Any information or ideas on this company? Perhaps you would have some suggestions on how to check on this or similar publishing houses? Thank you.
