Series is comprised of sheet music of James Mobberley’s compositions, and it houses the bulk of this collection’s materials. It is divided between boxes 1-11 (letter and legal size), boxes 18-26 (tabloid size), and Map Drawer 49 (oversized). It is also divided into two sections: professional compositions, and pre-professional, incomplete, and withdrawn works. Many scores, parts, and recordings of these works are also on digital format as well. Note: All legal- and letter-sized folders begin with box 1, but oversized sheet music folders begin with box 18. Pieces are listed in alphabetical order, but note the discrepancy in document size/box number. “MD” stands for Map Drawer.
