Mam Tor has published the award-winning anthology Mam Tor: Event Horizon. There are no fees for the work produced, nor are there the usual editorial restrictions. Mam Tor has not been created as a commercial venture, but as a forum for subcultural, underground, science fiction, horror or fantasy artists. Mam Tor is dedicated to producing creator driven works that might not ordinarily find a home on the bookshelf - their being too niche, radical or unquantifiable - despite the evident quality and commitment they display. This saw the launch of the critically acclaimed and award-winning anthology, Mam Tor: Event Horizon. Together with designer Tom Muller and friend John Bamber he set out to expand the company to start publishing more work. Sharp, who always has walked the fine line between commercial success and artistic freedom saw potential and an opportunity to use his publishing imprint as a way to offer the talent a stepping stone in the industry, while offering well known creators a playground where they could let their creativity run free without the usual editorial restrictions. The book gained success, and during Sharp's many convention visits he started to meet a lot of like-minded, and more important, unpublished artists and writers who couldn't seem to break into the industry because their work was considered too far removed of the mainstream market.

It, a personal artbook featuring previously unreleased art samples of Sharp, was initially a portfolio showcase he could send publishers.

During 2004, Mam Tor Publishing was established by Liam & Christina McCormack-Sharp to publish Sharpenings, The Art of Liam Sharp.
