A book and cassette file system for coordinating books and companion audio transcription cassettes includes a base and a pair of book ends. Each book end includes compartments for storing audio cassettes. A base is provided for supporting the books and the book ends and various mechanisms are illustrated for preventing the book ends from being displaced laterally. A projection extends from either the base or the book end and is received in one of a plurality of receptacles for securing each book end in a desired position along the base. Optionally, a keyway is provided in the base and a key projecting from a book end is engaged in the keyway. In a further embodiment, a spring anchored to one end of a keyway formed in the base is secured at its opposite end to one of the book ends. Another spring is anchored at the other end of the base and secured to the opposite book end.
