The Bedford Guide for College Writers by X.J. Kennedy et. al. was published in several configurations. The most complete guide contains three suppliments to the main book and is considered to be like an omnibus edition contianing four books. Only editions containing the entire 4 book configuration should be included here. The lack of any of the three suppliments makes that edition considerably different than one which contains all four or any specific three books. This group of editions contains all three suppliments to the main book. The best way to determine which group your Bedford Guide belongs in is the full title. The Bedford Guide for College Writers with Reader, Research Manual, and Handbook contains all suppliments.
