Are straight desks available with built-in shelving above the work surface?

Yes — a hutch unit is the most common way to add shelving above a straight desk. Hutches attach to the back of the desk work surface and provide cubbies, shelves, and sometimes enclosed cabinets for books, binders, and supplies. They're available in matching finishes and are sold separately or as desk-hutch package deals. OfficeFurniture2go.com offers many desk+hutch combos — call 1-800-460-0858.
