Tabula Rasa began in 1994 as a magazine devoted to both the history of horror and its present developments. Due to financial and time restraints, only seven issues were ever published in hardcopy format. In 2001, Carroll and Ward established Tabula Rasa as a website, expanding its focus to include Australian comics, Australian horror, role playing, Doctor Who, and Stephen King. The site also includes numerous interviews with speculative-fiction writers. Additional features include uploaded copies of David Carroll's fanzine Burnt Toast and his 'unpublished' Doctor Who novel Imperfect Copy.
Contributors to the website include Leigh Blackmore, Robert Hood, Kate Orman, Rod Williams, Rick Kennett, Ben Peek, and illustrator Jason Towers.
