In 1812，the year Charles Dickens wasborn, there were 66 novels published in Britain. People had been writing novelsfor a century—most experts date the first novel to Robinson Crusoe in1719—but nobody wanted to do it professionally. The steam-powered printingpress was still in its early stages；the literacy rate in Englandwas under 50％. Many works of fiction appeared without the names of the authors,often with something like “By a lady.” Novels, for the most part, were lookedupon as silly, immoral or just plain bad.
