Senior Library Clerk Practice Test

In library classification, the 900s are the area for history and geography. That part of the schedule includes works on history and biographies, so the field that fits the “900 history, biography” category is History, biography. The other subjects sit in different ranges: religion is in the 200s, literature in the 800s, and pure science in the 500s. So the best match for that category is the field combining history and biography.
