"Stock arrangements" are published orchestrations for instrumental ensembles--bands, small orchestras, or combos—that enable them to perform popular songs or piano works that previously either had been unpublished in any form, or published only as piano or piano-vocal works.

The lists found in the Jazz Stock Arrangements Research Guide are short bibliographies of "stock arrangements" found in the general collections of the Music Division at the Library of Congress. These arrangements are not digitized, as many are still protected by copyright, however, the lists serve as a guide to the vast collection of published jazz material held at the Library of Congress.
