Library Music, also known as source or mood music, was made for use in film, TV, advertising and radio. It is music given to TV stations and producers, but never commercially for sale. Similarly the sleeves are designed to represent the music not for commercial sales. These are LPs for purpose and function, not for pop charts, and as a result they look and sound like nothing else. The first edition of The Music Library came out in 2005. It brought together over 325 sleeves with information about these rare and elusive albums. This highly sought after book influenced both graphic artists and music collectors around the world, quickly becoming known as the music library 'bible'. The Music Library sparked a resurgence of interest in the subject over the last ten years, with many new libraries and recordings coming to light. As a result this revised and expanded edition contains twice the content, featuring 625 rare sleeves from 230 music library companies of the 1960s, 1970s and early 1980s. The amazing cover designs of over 100 newly discovered libraries are beautifully reproduced (alongside all the sleeves contained in the first book) accompanied by exhaustive updated captions.
