Concept
An audiobook (or a talking book) is a recording of a book or other work being read out loud. A reading of the complete text is described as "unabridged", while readings of shorter versions are abridgements. Spoken audio has been available in schools and public libraries and to a lesser extent in music shops since the 1930s. Many spoken word albums were made prior to the age of cassettes, compact discs, and downloadable audio, often of poetry and plays rather than books. It was not until the 1980s that the medium began to attract book retailers, and then book retailers started displaying audiobooks on bookshelves rather than in separate displays. The term "talking book" came into being in the 1930s with government programs designed for blind readers, while the term "audiobook" came into use during the 1970s when audiocassettes began to replace phonograph records. In 1994, the Audio Publishers Association established the term "audiobook" as the industry standard. Spoken word recordings first became possible with the invention of the phonograph by Thomas Edison in 1877. "Phonographic books" were one of the original applications envisioned by Edison which would "speak to blind people without effort on their part." The initial words spoken into the phonograph were Edison's recital of "Mary Had a Little Lamb", the first instance of recorded verse. In 1878, a demonstration at the Royal Institution in Britain included "Hey Diddle Diddle, the Cat and the Fiddle" and a line of Tennyson's poetry thus establishing from the very beginning of the technology its association with spoken literature. Many short, spoken word recordings were sold on cylinder in the late 1800s and early 1900s; however, the round cylinders were limited to about 4 minutes each making books impractical; flat platters increased to 12 minutes but this too was impractical for longer works. "One early listener complained that he would need a wheelbarrow to carry around talking books recorded on discs with such limited storage capacity.
