What is the weight capacity of bookcase shelves?

Commercial bookcase shelves are typically rated at 50–100 lbs of distributed load per shelf. A fully loaded shelf with standard binders (about 4–5 lbs each) can hold 10–20 binders per shelf comfortably within this rating. Steel shelving units have higher capacities — often 200+ lbs per shelf.
