Workbook is the 1989 debut solo album by American guitarist and singer Bob Mould, following the breakup of the influential rock band Hüsker Dü. The album has a strong folk influence and lighter overall sound than he had been known for, although heavy guitar features occasionally. Drummer Anton Fier and bassist Tony Maimone, both of Pere Ubu fame, served as Mould's rhythm section on the album and on the subsequent live shows. The single "See a Little Light" was a hit on the US Modern Rock chart.
