What is Bradford's Law?

A small core group of journals contains as many relevant papers as the next larger group, which contains as many as the next larger group still. Each zone contains roughly equal papers but 3× more journals.

How is Bradford's Law used in library science?

Helps libraries identify essential journal subscriptions. The core zone gives maximum coverage per subscription dollar for any given field.
