Sherlock Holmes is a fictional detective of the late 19th and early 20th centuries who made his first published appearance in 1887. He was devised by Scottish author and physician Sir Arthur Conan Doyle. Holmes is famous for his prowess at using logic and astute observation to solve cases. He is perhaps the most famous fictional detective, and indeed one of the best known and universally recognizable literary characters. Conan Doyle wrote four novels and fifty-six short stories featuring his creation. Almost all were narrated by Holmes' friend and biographer, Dr. John H. Watson, with the exception of two narrated by Holmes himself and two more written in the third person. The stories first appeared in magazine serialization, notably in The Strand, over a period of forty years. This was a common form of publication at the time: Charles Dickens' works were issued in a similar fashion. The stories cover a period from around 1878 up to 1903, with a final case in 1914.

In 1996 Audio Publishers Association established the Audie Awards for audio books, which is an equivalent to the Oscar for the talking books industry. The nominees are announced each year in January, and the winners are announced at a gala banquet in spring, usually in conjunction with BookExpo America. The quantity of the audio book enthusiasts continued to grow. They began joining into audio book clubs. By 1997 the Columbia House Audio Book Club had more than 150,000 members and the Herrik Company's Audio Book Club in Morristown, NJ had 215,000 members.
